A potential sode effect of biomagnification of an toxin in an ecosystem is?
A: population increase of a primary producer
B: population increase in secondary predators
C: population decrease of a secondary predator
D. population decrease of a primary producer
The correct answer is D. population decrease of a primary producer.
Biomagnification occurs when toxins or pollutants from the environment become more concentrated as they move up the food chain. As these toxins accumulate in higher trophic levels, they can have detrimental effects on the organisms at the lower trophic levels. Since primary producers (such as plants or algae) form the base of the food chain, they are particularly vulnerable to the effects of biomagnification. Therefore, the potential side effect of biomagnification is a population decrease of a primary producer (option D).
