The disappearance of a species when the last of its members dies.

Number of different species living in a specific area.

Variety of inheritable characteristics or genes in an interbreeding population.

In a biological community, the number and abundance of different species.

Variety of ecosystems in the biosphere.

Background Extinction

Gradual process of a species becoming extinct.

A large-scale dying out of a large percentage of all living organisms in an area within a short time.

Any material or organism in the biosphere, including water, soil, fuel, and plants and animals.

Overused of species with economic value - a factor in species extinction.

Habitat Fragmentation

Habitat loss from separation of an ecosystem into small pieces of land.

Any different environmental condition occuring along an ecosystem's boundaries.

Biological Magnification

Increasing concentration of toxic substances, such as DDT, in organisms as trophic levels increase in food chains or webs.

Water pollution from nitrogen-rich and phosphorus-rich substances slowing into waterways, causing algal growth.

Nonnative species deliberately or accidentally introduced into a new habitat.

Any resource replaced by natural processes more quickly than it is consumed.

Nonrenewable Resource

Any natural resource available in limited amounts or replaced extremely slowly by natural processes.

Use of resource at a rate that they can be replaced or recycled.

Found only in one specific geographic area.

Technique using living organisms to detoxify a polluted area.

Biological Augmentation

Technique of adding essential materials to a degraded ecosystem.

Model that shows many interconnected food chains and pathways in which energy and matter flow through an ecosystem.

An organism which preys on other organisms.

An organism which is preyed on by a predator.

Scientific study of all the interrelationships between organisms and the environment.
