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.
