As chemical pesticides move through the trophic pyramid, they may be amplified at each higher level in a process called
A) biomagnification.
B) trophic cascading.
C) competitive exclusion.
D) pyramidal decay.

Question

Quizplus · Accepted Answer

Biomagnification occurs as chemical pesticides are accumulated and amplified as they move through each level of the trophic pyramid. This can result in dangerously high levels of pesticides in top predators, such as birds of prey, which can have negative impacts on their health and survival. Trophic cascading refers to the indirect effects on lower trophic levels that result from changes in higher trophic levels, and is not directly related to pesticide accumulation. Competitive exclusion refers to the process by which one species excludes another from access to a particular resource, and pyramidal decay is not a recognized ecological process.
