Sientific study of interactions among organisms between organisms and their enviroment.

Part of earth in which life exists including land, water, and air or atmosphere.

Group of similar organisms that can breed and produce fertile offspring.

Group of individuals of the same species that live in the same area.

Assemblage of different populations that live together in a defined area.

A collection of all the organisms that live in a particular place, together with their nonliving enviroment.

Orqanisms that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer.

organisms that obtains energy from the foods it consumes; also called a consumer.

Network of complex interactions formed by the feeding relationships among the various organisms in an ecosystem.

Step in a food chain or food web.

Total amount of living tissue within a given trophic level.

Condition of earth's atmosphere at a particular time or place.

Average,year after year conditions of temperature and precipitation in a particular region.

4-1 Green House effect

Natural situation in which heat is retained in earth's atmosphere by carbon dioxide, methane, water vapor, and other gasses.

Biological influence on organisms within an ecosystem

Physical or nonliving factor that shapes an ecosystem.

Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions.

Growth pattern in which a populations growth rate slows or stops following a period of exponentional growth.

5-1 Carrying Capacity

Largest number of individuals of a population that a given environment can support.

Scientific study of human populations.

5-3 Demographic transition

Change in a population from high birth and death rates to low birth and death rates.

the development of highly productive crop strains and the use of modern agriculture techniques to increase yields of food crops.

6-2 Renewable Resource

Resource that can regenerate quickly and that is replaceable.

Harmful material that can enter the biosphere through the land air or water.

Biological diversity; the sum total of the variety of organisms in the biosphere.

6-3 Biological magnification

Increasing concentration of a harmful substance in organisms at higher trophic levels in a food chain or food web.
