scientific study of interactions between organisms and their environment

part of earth which life exists including land, water, and air or atmosphere

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

A group of individuals of the same species that live in the same area.

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

Collection of all organisms that live in a specific place.

organisms that capture energy from sunlight or chemicals and use that energy to produce food

Organisms that rely on other organisms for energy and food supply.

Complex networks of feeding relationships among various organisms in an ecosystem

Each step in a food chain or food web

The total amount of living tissue within a given trophic mass

Cycle in which elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another.

A substance that is scarce or cycles very slowly and the ecosystem is limited to that substance.

Day to Day condition of Earth's atmosphere at a particular time and place.

The average, year after year conditions of temperature and percipitation in a particular region

The natural situation when heat is retained by the layer of greenhouse gases in the atmosphere.

The biologicl influences on organisms within an ecosystem.

Physical and nonliving factors thay shape ecosystems

a full range of physical and biological conditions in which an organism lives and the way these organisms use those conditions.

Depends on when a population's growth slows or stops following a period of exponential growth.

The largest number of individuals a given environment can support.

The scientific study of human populations.

Demographic Transition

a dramatic change in birth and death rates.

The introduction of Modern agricultural techniques and the use of chemical fertilizers that greatly incresed the food supply

Resources that can regenerate if they can be replendished by biological cycles if they are nonliving.

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

The sum total of the genetically based variety of all organisms in the biosphere.

Biological Magnification

Process where concentrtions of a harmful substance increase in organisms at higher tropic levels in a food chain or food web. It effects the entire food web and top-level carnivores are at top risk.
