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