Depth of Water (meters) Dissolved Oxygen (mg O2 per liter) Amount of Algae/sq. meter (kilogram) 1 9.2 550 5 9.0 535 10 8.5 404 15 7.0 155 20 5.5 45 25 4.2 12 Consider the data regarding the growth of algae in a large lake, like the one illustrated above. Plants release oxygen as a by-product of photosynthesis. Draw a conclusion about other life forms in the lake, based on this data. A) All of the life forms in the lake can be found within the top 10 feet of water. B) As you increase in depth of water, plant density decreases while fish density increases. C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life present in the lake.
Algae growth produces a high concentration of oxygen on the surface, which decreases with depth. The less oxygen available in deeper strata, the fewer surviving forms of life. The correct option is C.
-----------------------------------------------------------------------------------------------------------
Available data:
Depth of Water Dissolved Oxygen Amount of Algae/sq. meter
(meters) (mg O₂ per liter) (kilogram)
1 9.2 550
5 9.0 535
10 8.5 404
15 7.0 155
20 5.5 45
25 4.2 12
According to this table,
On the surface, there is a higher amount of algae, and hence, more dissolved oxygen. As it gets deeper, algae amount decreases as well as dissolved oxygen.
If oxygen decreases with depth, it suggests that plants -oxygen producers- lack, probably due to the lack of sunlight reaching the bottom.
Other forms of life
Algae growth on the surface blocks the pass of light to the deeper strata.The lack of light in deeper strata affects plants' growth.If there are no plants in deeper areas, there is no dissolved oxygen.Since animals need oxygen, they probably can not survive in deep regions.With no oxygen, the bottom turns into an anaerobic environment, in which anaerobic bacteria can survive.
These conditions can be related to eutrophication.
Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.
This oversupply, mainly of nitrogen or phosphorous, favors phytoplankton multiplication, especially cyanobacteria.
Cyanobacteria overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.
Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.
These sediments suffer decomposition in the absence of oxygen. Anaerobic bacteria act and produce fermentation.
Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
The continued increase in decomposition and fermentation produces a bad smell and toxicity.
The result of eutrophication is the stratification of the water mass:
First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer. The second layer might have oxygen available for the animals. In the third layer, there is no oxygen, so life is impossible for animals or plants. In the fourth layer, there are animals and plant remains in the process of sedimentation. At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.Options:
A) All of the life forms in the lake can be found within the top 10 feet of water. FALSE. Depends on the conditions and the species.
B) As you increase in depth of water, plant density decreases while fish density increases. FALSE. Plant and animals density decrease, as available oxygen decrease.
C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. TRUE.
D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life is present in the lake. FALSE. Light does not reach the bottom, so there are no plants there. Plants also depend on oxygen, not only animals.

which source of calories causes the body to expend the most energy during digestion?
The consumption of energy during digestion is known as the thermic effect of food.
Consuming food is how we get the energy needed to sustain the basic functions of our organisms. Digesting this food, however, also takes up energy. In fact, about 10% of the energy we expend daily is allocated towards the digestion and storage of food and nutrients. This is known as the thermic effect of food.
On average, the food with the highest thermic effect is that of vegetables and fruit with high water compositions. This, however, falls a bit out of the scope of the question given that these foods are often very low in calories. The food that is high in calories and has a high thermic effect is protein. On average, proteins consume 20-30% more energy to digest than other sources of calories.

True
False
Everything including you and me is made up of matter
True or False
Answer:
Technically, yes.
Explanation:
Depends on your point of view.
NOTE: This excludes light, and photonic interaction. That technically doesn't make up anything, because it has no mass.
Matter is anything that has mass and takes up space. Due to E=MC*2, energy and mass are relative, even though a small amount of mass, has a large amount of energy. So let’s backtrack. Matter is anything. Matter is energy. Matter is nothing? What about in an atom. Or in the vacuum of space? In an atom, between the nucleus, and the electron cloud, there is empty space. In the vacuum of space, most people think there is nothing. Just emptiness, until the next star, or the next planet. That is 100% wrong. I guess they are either thinking too hard or not enough. The vacuum of space actually has energy. Just a small amount of it. It takes up space, that check’s off. It has mass (excluding photons), that check’s off. And yes, it has energy. SO, since energy and matter are interchangeable, everything is made of energy, even though not everything is made of matter. Certain types of energy, sound, heat, light, are not made of energy. Does that mean that photons are not made of Matter? Well, sort of. They have no mass, so technically not, but they do have space and exert a force, which is also mysterious. So, I hope this confused you a little bit, with matter being energy, but not energy being matter. Here is something to spark the imagination: Is fire a solid, a liquid, or a gas

C
BD
Answer:
B) Oxygen and E) Carbon Dioxide
Explanation:
Cellular respiration has a general chemical equation as:
[tex]C_6H_{12} O__6[/tex] [tex]+6O_2[/tex] ⇒ [tex]6CO_2[/tex] [tex]+6H_2O[/tex]
glucose + oxygen ⇒ carbon dioxide + water
Photosynthesis has a general chemical equation as:
[tex]6CO_2[/tex] [tex]+6H_2O[/tex] ⇒ [tex]C_6H_{12} O_6[/tex] [tex]+ 6O_2[/tex]
carbon dioxide + water ⇒ glucose + oxygen
Reactants are on the left side of the equation while products are on the right. You can see that the products in cellular respiration are carbon dioxide and water, these also are the reactants in photosynthesis. So (B) Oxygen and (E) Carbon dioxide are the answers.

The answer is Water and Carbon Dioxide
