Answer 1

Bioaccumulation refers to the accumulation of pollutants in organisms over time. Eating big fish that accumulate the most pollutants is not recommended. Pesticides can impact organisms at different trophic levels resulting in bioaccumulation.

Step-by-step explanation:

Bioaccumulation refers to the process in which pollutants or toxins accumulate in the bodies of organisms over time. It is a result of organisms ingesting or absorbing pollutants from their environment, which then accumulate in their tissues. Eating big fish that accumulate the most pollutants in their bodies is a bad idea because when we consume these fish, we can be exposed to high levels of toxins. For example, large predatory fish like tuna and swordfish are known to accumulate high levels of mercury, which is a toxic metal.

On the other hand, it is not true that only small microorganisms will be affected if a farmer allows pesticides to leak into a pond. Pesticides can enter the food chain and impact organisms at different trophic levels, leading to bioaccumulation. Small organisms may absorb pesticides, but those pollutants can be transferred to larger organisms when they are consumed.
