Number of different species living in a specific area.

Biological community and all the nonliving factors that affect it.

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

Variety of inheritable characteristics or genes in an interbreeding population.

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

Background Extinction

Gradual process of a species becoming extinct.

Biological Manification

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

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

Water pollution from nitrogen-rich and phosphorus-rich stances flowing into waterways, causing galga overgrowth.

Habitat Fragmentation

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

Nonnative species deliberately or accidentally introduced into a new habitat.

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

Materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain.

the overuse of wildlife and plant species by people for food, clothing, pets, medicine, sport and many other purposes.

Biological Augmentation

the addition of bacterial cultures required to speed up the rate of degradation of a contaminant.

the use of either naturally occurring or deliberately introduced microorganisms or other forms of life to consume and break down environmental pollutants, in order to clean up a polluted site.

native or restricted to a certain country or area.

Nonrenewable Resource

Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years.

Any resource, such as wood or solar energy, that can or will be replenished naturally in the course of time.

Use of resources at a rate that they can be replaced or recycle.
