Question

The cartoon below addresses a growing concern:

What impact will the process shown in the image have on humans if they occupy the last trophic level? Explain.

Answer 1

If humans occupy the last trophic level in the food chain, the accumulation of pesticides in organisms at lower trophic levels could lead to serious health risks due to biomagnification. For example, a food chain from cabbage to caterpillar to bird culminates in humans, who may consume contaminated birds, thus facing increased exposure to harmful chemicals.
