Question

which of these occurs when an organism absorbs a toxic sul at a rate faster than the organism can lose it via excretion and catabolism?
erosion
growth and reproduction
eutrophication
bioaccumulation

Explanation:

Bioaccumulation is the process where an organism absorbs a toxic substance at a rate faster than it can excrete or metabolize (catabolize) it. Erosion is related to the wearing away of soil or rock. Growth and reproduction are normal life - processes. Eutrophication is about nutrient enrichment in water bodies leading to excessive plant growth. Only bioaccumulation matches the description in the question.

Answer:

bioaccumulation
