Few producers live deep below a lake's surface. Suggest an explanation for this pattern

Answers

Answer;

-Since sunlight is where most of the energy in an ecosystem comes from, there is less sunlight deep in a lake meaning less organisms can survive.

Explanation;

-The reason why many plants don't live deep below a lake's surface is because lakes don't normally have chemical vents. Thus, making it hard for producers to find any sources of energy in the dark, deep waters of the lake.

-Since the deepest parts of a lake receive the least light, the ability of submerged macrophytes (plants larger than algae) to establish colonies is limited.

-The combination of low oxygen levels and low light limits the growth of plant communities at great depths; many plants living in very deep water have adaptations such as elongated stems or long structures so that at least some of the plant is in the water nearer the surface where it can photosynthesis.

Producers are living organisms that enables the production of food or is able to produce their own food through the photosynthetic mechanism of their structures which has helped many organisms survive. 

This is because there is not enough sunlight and air which are needed for the producer to make food.

c) an artificial mutagen.
d) another name for unmethylated cytosine.
e) a natural mutagen.

Answers

Answer:

E) a natural mutagen.

Explanation:

Aflatoxin is a toxin byproduct produced by the fungi especially Aspergillus molds which grows attached to the roots of various crops like the peanuts, wheat and many others.

The aflatoxin is considered a carcinogen and a mutagen as it causes certain changes in the structure of DNA.  The aflatoxin mainly affects the liver and causes a mutation in the genes of the liver and since the aflatoxin is produced naturally by the molds, therefore, is considered a natural mutagen.

Thus, option-E is correct.
