Bioaccumulation - CORRECT ANSWER-The accumulation of a substance, such as
a toxic chemical, in various tissues of a living organism.
Biomagnification - CORRECT ANSWER-Accumulation of pollutants at successive
levels of the food chain
abiotic factors - CORRECT ANSWER-natural control measures within the
environment.
EX: climactic factors, air/water pollution, topographic features.
Biological Control - CORRECT ANSWER-The use of natural enemies to control
pests.
EX: Predators, Parasites, Pathogens
Cultural Control - CORRECT ANSWER-These are Practices that reduce pest
establishment, reproduction, dispersal and survival.
EX: Mowing, irrigation, aeration, fertilization and sanitation.
Genetic control - CORRECT ANSWER-Making use of plant varieties that are
