Question

what term is used to describe an increased concentration of toxic chemicals as we move up the food chain? biomagnification biodegrading

Explanation:

To determine the correct term, we analyze the options:

• Biomagnification refers to the process where the concentration of toxic substances increases as we move up the food chain (organisms at higher trophic levels accumulate more toxins because they consume multiple organisms from lower levels, each with a small amount of toxin, leading to a higher overall concentration in the higher - level consumer).
• Biodegrading refers to the process of breaking down organic substances by living organisms (like bacteria or fungi breaking down dead plants or animals), which is not related to the increase of toxic chemicals in the food chain.

Answer:

A. biomagnification
