How will you justify the need of saprophytes in the ecosystem?
Answer:
It is because they are extremely beneficial. The reason saprophytes are so beneficial to the environment is that they are the primary recyclers of nutrients. They break down organic matter so that the nitrogen, carbon, and minerals it contains can be put back into a form that other living organisms can take up and use.

A variety of plant populations can be found in a prairie. What would be the most likely effect on a plant populations if there was a significant decrease in rainfall? A- Competition for water among the plants would decrease B-Competition for water among the plants would increase C- it would increase the ability all the plants reproduce D-it would have no effect on the plant populations.
The most likely effect on plant populations in a prairie if there was a significant decrease in rainfall would be an increase in competition for water among the plants. So, the correct answer would be B - Competition for water among the plants would increase.
What is a plant population?Plants are dependent on water for a variety of processes, including photosynthesis, growth, and reproduction. In a prairie ecosystem, different plant species coexist and comete for limited resources such as water, nutrients, and sunlight. A decrease in rainfall would lead to a reduction in the available water supply, which would result in increased competition for water among the plants. As water becomes scarcer, plants will need to adapt to survive. Some plants may be better able to tolerate dry conditions or have deeper roots that can access water from deeper in the soil.
Hence, So, the correct answer would be B - Competition for water among the plants would increase.

Farmers spray pesticides on their plants to protect the plants from being eaten by insects. Some individual insects have a genetic mutation that makes
them resistant to the toxins in the pesticides. Which statement best describes how only a few resistant individuals resulted in the pesticide becoming
ineffective?
o The resistant insects are able to survive to reproduce and create a population that is also resistant
The resistant insects grow larger and eat less of the plants.
The resistant insects change the toxin on the plants, making it safe for others.
o
The resistant insects eat the contaminated surface and leave the rest for others
The correct option here will be A)
only a few resistant individuals resulted in the pesticide becoming
ineffective because The resistant insects are able to survive to reproduce and create a population that is also resistant.
How do insects become resistant to pesticides over time?spraying the same pesticide often enables the pests to develope resistant genes which enable them to survive. Insects without resistance genes die when exposed to insecticides, allowing individuals with resistance genes to survive and breed, resulting in more resistant insects. The number of resistant insects grows with each generation. hence the pesticide often becomes ineefective over time.
Hence The resistant insects are able to survive to reproduce and create a population that is also resistant.
other options are incorrect because:
resistant insects growing larger and eat less of the plants des not contribute to pesticide resistance.The resistant insects cannot change the toxin on the plants this is an impossible thing.The resistant insects eating the contaminated surface and leaving the rest for others wont result in the pesticide becoming ineffective,learn more about insect resistance here:

What are the environmental problems of this ecosystem and what would be the solution to these problems?
Answer:
Air pollution is one of the biggest threats to the environment and affects everyone: humans, animals, crops, cities, forests, aquatic ecosystems, and much more. Since the Industrial Revolution, people have been polluting the Earth like never before. There is seldom a place today that has not been subjected to pollutants in one shape or another. Air pollution can be defined as an alteration of air quality that can be described by measures of chemical, biological or physical pollutants in the air. Therefore, air pollution means the unwanted presence of impurities or the strange rise in the proportion of some components of the atmosphere. It can be categorized into 2 areas: visible and invisible air pollution. Air pollution is caused by the presence in the atmosphere of harmful substances, mainly built by human activities, even though occasionally it can result from biological phenomena such as volcanic eruptions, dust storms, and wildfires, also depleting the air quality. The basic answer for air pollution is to drive away from fossil fuels, replacing them with alternative fuels like solar, wind, and geothermal. Creating clean energy is necessary. But equally crucial is to reduce our consumption of fuel by assuming trustworthy habits and using more efficient machines. From planning to destruction, the green building seeks to create environmentally accountable and resource-efficient systems to reduce its carbon footprint. In addition, monitoring air pollution levels has evolved into extremely necessary to detect pollution highlands, better manage air pollution, and ultimately enhance air quality.

Which statement describes the geologic features?
Layer K is the oldest.
Layer W is the youngest.
Fault Q occurred before layer K was deposited.
Layers B, W, and E were deposited after fault Q occurred.
Answer:
The correct answer is option C.
Explanation:
The correct answer is Fault Q occured before layer K was deposited. This should be correct on the Edge Unit Test. Hope this helps!
The statement that describes the geologic features is Layers B, W, and E were deposited after fault Q occurred. Hence option D is correct.
The fault Q is a line that cuts through the rock layers, and it is clear that the fault Q cuts through layers B, W, and E, but not layer K. This means that the fault Q must have occurred after layer K was deposited.
The other statements are not correct. Layer K cannot be the youngest, because it is cut by the fault Q. And the fault Q cannot have occurred before layer K was deposited, because the fault Q cuts through layer K.
Therefore, the only statement that correctly describes the geologic features is D) Layers B, W, and E were deposited after fault Q occurred.

Help if you know about overfishing. What two suggestions are given to help stop overfishing?!
Answer:
YOU CAN HELP STOP OVERFISHING
The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.
Here is what needs to happen…
CREATE MORE MARINE PROTECTED AREAS
Currently, less than two percent of the world’s oceans are protected in marine parks; and less than one percent of the oceans are protected from any kind of fishing. More no-catch zones must be established to allow fish populations and their ecosystems to recover and replenish themselves to ensure fishing for future generations.
The Marine Conservation Institute wants to increase that number tenfold, and have ten percent of our oceans become Marine Protected Areas by 2020. We would like to see 20 percent of the ocean protected to ensure increased healthy fish stocks in the future.
STOP TRAWLING
Trawling drags huge nets through the ocean that scoop up every animal and the ecosystem in its pathway, resulting in massive wasteful bycatch – dead fish are returned to the sea because they weren’t the target fish. We don’t have that kind of sea life to waste. Though there are many programs that focus on decreasing by-catch, and worldwide there are small regions where bottom trawling is banned or limited, these measures aren’t enough. Trawling needs to be banned outright.
Facing depleted fish stocks with an imminent and complete collapse, the Chinese government imposed a trawling ban in Hong Kong’s waters that took effect in December 2012. They did this by buying fishing vessels fitted for trawling, and supporting deckhands who’d be affected by the reduced amount of fish caught. Bans like this in the waters of Alaska, Chile and elsewhere are being fought for by environmental organizations. They need our help!
WORLDWIDE CATCH SHARES
Catch shares is a system of fishing management that is proven to allow fish stocks to replenish, while saving the livelihoods of fishing communities by preventing a sudden collapse. A total allowable catch is established, using scientific data about the health of fish stocks and the environment in a certain area, and catch shares are licensed out to each fishing business telling them exactly how much of each seafood species they’re allowed to catch.
Using catch shares makes seafood more valuable, meaning a higher, more predictable profit for fishermen, while protecting the environment. As opposed to limiting the time of a fishing season—driving fishermen on a mad dash to make their living in a short time and use trawling or other unsustainable fishing methods to do it—catch shares foster communication and stewardship.
A study of American and British Columbian catch shares systems found that over a decade, the total allowable catch increased 19 percent, by-catch decreased by 66 percent, and fishermen made 68 percent more money while having one-third fewer accidents on the job. And 100 percent of fishing businesses complied, rarely going over their limit. It’s a proven system that needs to be implemented worldwide, and strengthened where it does exist, like the Common Fisheries Program in Europe or on the Pacific Coast of the US and Canada.
