C.it changes DNA,but it is random
The question is incomplete as it does not have the attached figure and the options which are:
A.) The population of frogs will decrease because of increased predation by snakes.
B.) The population of storks will increase because of decreased competition with eagles.
C.) The population of gnats will decrease because of a decrease in the amount of grass available.
D.) The population of grass will decrease because of increased predation by rabbits.
E.) The population of snakes will increase because of decreased predation by eagles.
Answer:
Option-A and E
Explanation:
In the given question, a structure of a complex food web has been provided in which the organism present at the different trophic level are affected by different factors including-
1. The population of Eagles (top consumer) has decreased due to human activities. Since the number of eagles has declined therefore the number of organisms on which it feeds will increase (snakes in the given question) due to no predation.
2. The population of rabbits (primary consumer) has decreased due to a virus. Since the number of rabbits will decline therefore the snakes will now shift eat more frogs and therefore the number of frogs will decline.
Thus, the selected options are correct.

Answer:
decomposer decomposes :) so it breaks down the organic matter into simpler compounds. it's very important process because complex compounds that build living organisms are not absorbable for other organisms, thus chemical cycling wouldn't be possible and the whole ecosystem would shut down. dead plants and animals would be everywhere and new organisms couldn't be born/grown. mold breaks down dead organic matter like dead trees. as the result simple compounds come into existence and can be assimilated by plants
