Competition- An interaction to gain a share of a limited resource. An example is an interaction between vultures, hyenas and a dead hippo.
What is competition?When resources are insufficient to meet the demands of all the organisms living in a community, competition occurs when organisms of the same species or other species use the same resources.
Within a species, either all individuals get some of a resource they need, like food or space, or some get enough to meet their needs while others, who are shut off from the resource, perish or are compelled to live in a less desirable or marginal location. The majority of the time, young people in a population suffer negative effects.
The less likely it is that two different species may coexist in the same location, the closer their requirements must be. Although they may be forced into direct competition when resources are low, species with comparable requirements can occasionally coexist in the same region if they differ in behavioural ways like feeding patterns, breeding preferences, or activity periods. When two species coexist in small populations, their members frequently have smaller-than-average bodies or have a poor reproductive rate.

(a) Wind blows the seeds of a dandelion into a pond. The seeds fail to grow - abiotic factor
(b) A population of grasshoppers eats all the available food, and their numbers drop dramatically - Biotic factor
(c) A bacterium causes a deadly disease in a herd of reindeer, and some of them die - Biotic factor
(d) Plants growing beneath the trees in a forest are unable to get enough sunlight - an abiotic factor
What are biotic and abiotic factors?Biotic factors are living or once-living organisms that affect the ecosystem, such as plants, animals, fungi, bacteria, and other microorganisms. These factors interact with each other, influencing each other's growth and survival, and collectively make up the living components of an ecosystem.
Abiotic factors, on the other hand, are non-living physical and chemical components of the ecosystem, such as water, air, soil, temperature, sunlight, minerals, and nutrients. These factors shape the physical environment of the ecosystem and have a profound influence on the biotic factors living within it. For example, the availability of water and nutrients can greatly affect the growth of plants.

Wildebeests: A Keystone Species Use the data provided to answer the question below in CER format. Make sure to use at least two pieces of evidence to claim and provide reasoning. FIRE! Fire is actually an important component of savanna ecosystems. Fire kills young trees and seedlings, reducing the number of big adult trees that grow over time. Since trees compete with grasses for light and soil moisture, fire actually helps the grasses and keeps the savannas open. Dr. Rico Holdo, a professor at the University of Missouri, and his colleagues modeled and wrote about the interactions of fire, rain, grasses, trees, and the various animals in the Serengeti. The interactions get complicated quickly, but I’ll try to give you a run-down of how they see fire acting in this ecosystem. First, as I’ve mentioned, fire suppresses trees and encourages grasses. If you have both fire and rain, but no animals, then something interesting happens: the rain encourages the trees, but it encourages the grasses, too. As the grasses get taller, there is more fuel for fire, and the fires become more widespread and more damaging. These fiercer fires really hurt the trees – in fact, the damage from fires (because of more rain) is more important than the extra boost the trees get directly from the rain. So more rain actually means fewer trees. With me so far? We’re now going to throw animals into the mix – well, at least some of the animals. Let’s talk about the grazers. The grazers eat the grass, and this reduces the fuel available to fire. If you have a lot of grazers, like we do in the Serengeti, the grass height is reduced a lot. That means fewer fires and that rain once again helps the trees. Further, many of the grazers are migratory and move around the landscape a lot. They don’t eat the savanna grasses in a neat, tidy, organized way. Instead, they create a patchy mosaic of grass heights, and with those different grass heights come different susceptibility of patches of grass to burn. With rain and fire and grazers, we now have a landscape of grasses of different lengths, patchy fires, and some areas dense with trees and some areas with fewer trees. All that variation means more diversity – more diversity of the grasses, plants, and trees, and more diversity of the animals that rely on them. All that diversity is due, in part, to fire. A Keystone species is a plant or animal that plays an important and unique role in how the ecosystem functions without the key stone species to ecosystem would be very different. One scientist identified Keystone specie it to look as how changes to their abundance (number ) affect other organisms. Often, there are many indirect effects of changes to ecosystems. Claim The wildebeest in the Serengeti are a keystone species. What evidence supports this claim? (Make sure to provide reasoning)
Because of their grazing habits, which limit the amount of fuel available for fires and support the preservation of a diverse ecosystem with a range of grass heights and tree densities, wildebeest in the Serengeti are a keystone species.
The wildebeest is a keystone species in what way?Wildebeest help new, diverse plants grow by grazing vegetation that could otherwise serve as wildfire fuel and reducing its overall amount. As a result, other species, such birds and butterflies, have better habitat quality, making wildebeest a keystone species.

(b) Lice feed harmlessly on the feathers of birds. commensalism
(c) A cowbird removes an egg from a robin's nest and replaces it with one of its own. commensalism
(d) An orchid plant grows on the branch of a tree. The tree remains healthy. commensalism
Answer:
A: Mutualism
B: Parasitism
C: Commensalism
D: Commensalism
Explanation:
Mutualism is a relationship between two species of organisms in which both benefit from the association.
Commensalism is a type of relationship between two species of a plant, animal, fungus, etc., in which one lives with, on, or in another without damage to either.
Parasitism is a relation between organisms in which one lives as a parasite on another.
PART A: The yucca plant is necessary for the yucca moth larvae to live because it is their only source of sustenance. The moth pollinates the plant, and in return, the plant provides sustenance for the moth, creating a harmonious partnership.
PART B: Different types of biting lice, fleas, and louse bugs are commensals because they graze safely on avian feathers and the skin flakes shed by animals.
PART C: A female cowbird looks for other species' female birds that are busy depositing eggs in a quiet manner. After locating an appropriate host, the cowbird will break or take one (or more) eggs from the resident bird's nest while it is gone and substitute them with one (or more) of her own.
PART D:
Commensalism is the term used to describe the interaction between plants and orchids. When two species coexist, one of the species benefits while the other is unchanged.

Explanation: Species that rely on hummingbirds for pollination, instead of the insects their ancestors did, have acquired a number of ‘pro-bird’ and ‘anti-bee’ traits; nectar that is particularly sucrose rich, flowers that are brightly colored but unscented (smell is vital for insects to find flowers, but vision is the key for birds), and various adaptations to their flowers to allow easy access for hummingbirds.
A tsunami brings a bunch of new sand onto a beach in a coastal region and new
sand dunes develop. This region will undergo
succession
to become a climax community
Answer:
The statement is incorrect.
Succession is a gradual and predictable change in the species composition of an ecosystem over time, starting from bare rock or sand and ending in a stable, self-sustaining community called a climax community.
In the scenario described, the deposition of new sand and the formation of new dunes can provide new habitats for pioneer species, which are the first to colonize disturbed areas. These species are usually opportunistic and fast-growing, such as grasses and shrubs. Over time, as these species die and decompose, they contribute to the formation of soil, which allows for the establishment of other species, such as trees and woody plants.
However, since the scenario involves a coastal region, the newly formed sand dunes can be highly vulnerable to erosion and flooding, which can interrupt the successional process and prevent the establishment of a climax community. In addition, the deposition of new sand can also affect the chemical and physical properties of the soil, which can limit the growth of certain plant species and affect the food web of the ecosystem. Therefore, it is not certain that the region will undergo succession to become a climax community.

Which statement describes how mutations lead to variation within a species?
A. They produce new inherited traits by changing the order of bases in DNA. B. They result from copying the genes of one parent before an offspring is produced.
C. They cause the genes of different individuals to mix during sexual reproduction.
D. They change the trait that a certain gene produces in members of the species.
The statement "They produce new inherited traits by changing the order of bases in DNA" (option A) best describes how mutations lead to variation within a species.
What is mutation?Mutation is a process that generates changes in the DNA sequence of an organism's genome. It can be defined as a permanent alteration in the nucleotide sequence that makes up the genetic material of an organism. Mutations can occur spontaneously, as errors in DNA replication or as a result of exposure to external factors such as radiation, chemicals, or viruses.
Mutations can also occur during meiosis, which is the process of cell division that produces gametes (sperm and eggs). Mutations are the primary source of genetic variation within a species, and they can lead to the evolution of new traits and ultimately new species over long periods of time.

Arable land is used to grow crops and feed livestock.
True
False
Answer:
True.
Explanation:
Arable land is defined as land that is suitable for farming, and is typically used for the production of crops and livestock feed. The term "arable" is often used to describe land that has been cultivated, plowed, and is ready for planting. This land is usually nutrient-rich and capable of supporting a variety of crops such as wheat, rice, corn, and soybeans, as well as forage crops for livestock such as alfalfa, clover, and grasses.
Farmers rely on arable land to produce food and feed for animals, and this land is a crucial resource for meeting the world's growing demand for agricultural products. Arable land is a finite resource, and it is important to use it efficiently and sustainably to ensure that future generations have access to the resources they need to produce food and feed for a growing global population.
Regarding the consumption of animal fats, why should larger mammals be avoided?
Larger mammals have far less protein per serving.
Larger mammals are more likely to transmit Salmonella.
The fat in larger mammals has accumulated more toxic substances.
The fat in larger mammals includes fewer omega-3 fatty acids.
Answer:
Consuming animal fats from larger mammals, such as cows, pigs, and sheep, may not be considered healthy in excess due to their high levels of saturated fat, which can increase cholesterol levels and the risk of heart disease. Moreover, larger mammals tend to accumulate a higher concentration of toxins such as mercury, PCBs, and dioxins in their tissues, which can pose health risks when consumed. Therefore, it is recommended to consume animal fats from leaner options or in moderate quantities.
Insects can show three types of development. One of them, holometaboly (complete development), consists of the stages of egg, larva, pupa and sexually mature adult, which occupy different habitats. Insects with holometaboly belong to the most numerous orders in terms of known species. This type of development is related to a greater number of species due to the a) protection in the pupa stage, favoring the survival of fertile adults. b) production of many eggs, larvae and pupae, increasing the number of adults. c) exploration of different niches, avoiding competition between life stages. d) food intake at all stages of life, ensuring the emergence of adults. e) use of the same food in all stages, optimizing the body's nutrition.
Answer:
Three major types of insect development: a) Ametabolous development typified by the silverfish, b) Hemimetabolous development typified by the cockroach; in some hemimetabola such as termites and grasshoppers there may be more than one stage with wing pads that could be called nymphal; c) Holometabolous development
The correct answer is option C) exploration of different niches, avoiding competition between life stages.
Each phase of development presents a different habitat and niche, which prevents competition between species, that is, intraspecific competition. In this way, the effectiveness of the animal within its environment is increased, as well as its adaptation to the environment.
The other alternatives highlight stages of development that exist, but are not related to the increase in the number of species or to the justification presented.
what pattern do you identify in the data?
The identified pattern that is seen here is that : pairing bases (AT and GC) are both very close in numbers . The values are sometimes off by just 0.5
What is the Chargaff rule?The Chargaff rule, also known as Chargaff's ratios or base pairing rules, states that in a double-stranded DNA molecule, the amount of adenine (A) is equal to the amount of thymine (T), and the amount of guanine (G) is equal to the amount of cytosine (C). This is sometimes expressed as A=T and G=C.
Erwin Chargaff, an Austrian-American biochemist, discovered this rule in 1949 by analyzing the base composition of DNA from various species. He found that the amounts of A, T, G, and C in DNA differed between species, but within a species, the ratios between A and T, and between G and C, were always roughly equal.
