Biological Magnification

As human beings occupy the top level in any food chain, the maximum concentration of these chemicals get accumulated in our bodies. This phenomenon is known as

• Biological magnification

• Biological accumulation

• Chemical magnification

• Chemical accumulation

accumulation of increasingly large amounts of a toxin within the tissues of organisms at each successive trophic level

• nonpoint pollution

• thermal pollution

• biological magnification

• water pollution

Which term best describes this ecological phenomenon?

• global warming

• loss of biodiversity

• biological magnification

• loss of genetic diversity

Which of the following best describes the term biological magnification?

• The buildup of non-biodegradable chemicals in consumers as they are passed up the food chain

• When members of a crowded population are at odds for food, water, space, and other resources

• Using the earth's resources more carefully, and preserving and restoring natural habitats

• When food, water, and space are limited, causing carrying capacity to be reached

What is biological magnification?

• The increase in concentration of pollutants in organisms at higher trophic levels

• The decrease in biodiversity due to pollution

• The increase in population size due to pollution

• The reduction of pollutants in the environment

How does biological magnification affect human health?

• It reduces the risk of diseases

• It increases the concentration of harmful chemicals in humans

• It improves nutritional value of food

• It has no effect on human health
