Question

You are an aquatic biologist studying a small lake. The stream that drains into this lake runs by croplands. You are detecting a pesticide called atrazine in the insects and worms that live in the lake, but the predatory birds such as herons and egrets have very high concentrations of atrazine in their blood. The birds prey on the frogs and small fish. What process explains the high atrazine level in the birds?

A. antagonistic interaction
B. persistence
C. chronic effect
D. biological magnification
E. none of these answers

Answer 1

Answer:

e

Explanation:

the reason the birds have such a high concentration is because the food they eat has it and the food's food has so it becomes a high amount

Answer 2

The process that explains the high level of atrazine in birds is due to biological magnification.

What do you mean by Predators?

Predators may be defined as an animal that lives mostly by killing and eating other animals for the purpose of food.

Biological magnification may be defined as the accumulation of a chemical by an organism from water and organisms living in the water. The birds eat all those insects and worms that already have a high concentration of atrazine. So, this high level of atrazine in birds has arisen from the prey species.

Therefore, the process that explains the high level of atrazine in birds is due to biological magnification.
