Question

Which of the following is a consequence of biological magnification (biomagnification)?
a. Toxic chemicals in the environment pose greater risk to top-level predators than to primary consumers.
b. The amount of biomass in the producer level of an ecosystem decreases if the producer turnover time increases.
c. Populations of top-level predators are generally smaller than populations of primary consumers.
d. Only a small portion of the energy captured by producers is transferred to consumers.

Answer 1

Answer:

Option (a).

Explanation:

Biological magnification may be defined as  the increase in the concentration of the harmful chemicals at the top levels in the food chain. The chemical or substance may not get degraded and accumulate in the higher tropic levels.

These toxic chemicals pose greater problem to the environment.  The toxic substance pose greater problem to the top level predators than the primary consumers because top predator directly feed on the primary consumers. The toxic chemicals get accumulate in their tissue.

Thus, the correct answer is option (a).

Answer 2

The consequence of biological magnification is that in the environment the toxic chemicals exhibit greater threat to the top-level predators than to primary consumers.

What is biomagnification?

It is illustrated as the accumulation of a specific substance in the body of the organisms at distinct trophic levels of a food chain. The substance or the chemical may not get degrade and thus get accumulate in the higher trophic levels.

These toxic chemicals exhibit greater threat to the environment. The toxic component exhibit greater issue to the top level predators in comparison to the primary consumers as the top predator feed directly upon the primary consumers. These toxic components get amassed within their tissue.

Thus, the correct answer is option a.
