Question

poisons such as ddt build up in lakes and streams due to runoff. then they * 1 point
enter the food chain. once in living organisms, the poisons are not broken
down and their concentrations increase as they are passed along the food
chain. which term best describes this ecological phenomenon?

loss of biodiversity

global warming

loss of genetic diversity

biological magnification

Explanation:

Biological magnification refers to the process where the concentration of a substance (like a poison) increases as it moves up the food chain. In this case, DDT builds up in organisms and its concentration increases along the food chain. Loss of biodiversity is about a decrease in the variety of species. Global warming is related to the increase in Earth's temperature. Loss of genetic diversity is about a reduction in genetic variation within a species. None of these other terms describe the phenomenon of a substance increasing in concentration along the food chain.

Answer:

Biological magnification
