Biomagnification - (ANSWER)Accumulation of pollutants at successive levels of
the food chain
abiotic factors - (ANSWER)natural control measures within the environment.
EX: climactic factors, air/water pollution, topographic features.
Biological Control - (ANSWER)The use of natural enemies to control pests.
