Population

A group of the same type of organisms.

Population Growth

The growth of a population by size and number.

S-Curve

J-Curve

Population Growth Rate

Population growth rate is how fast a population increases over a span of time.

Exponenial Growth

Community

A group of different organisms that interact wih eachother.

Watershed

A watershed is an area of land where rain water, streams and small rivers all drain into one large area of water such as a large river, lake or the ocean.

Climax Community

A climax community is a community that has grown to its fullest.

Ecosystem

The combined abiotic and biotic factors living together in the environment.

Wetlands

A wetland is an area of land that has water in it. For example wetlands include swamps, marshes, and bogs.

Biodiversity

Genetic

Genetic biodiversity is having a number of different organisms living in an ecosystem.

Species

Species biodiversity is having a large number of different animals in an ecosystem .

Ecosystem

Ecosystem biodiversity is having a large number of different ecosystem types in a single biome.

Hot Spots

Hot spots are ecosystems with a large capacity of organisms living in them. They are mostly found on and near the equator.

Factors in Nature

Biotic Factors

Biotic Factors are all living organisms in an ecosystem.   Examples: grass, trees, moss, fish, dogs, cats, bears, humans etc.

Abiotic Factors

All non-living things in an ecosystem. Example: rocks, water, snow, sand, mud etc.

Limiting Factors

Limiting factors are factors in an ecosystem that keep the population in check. If ecosystems didnt have limiting factors the population would grow to unsustainable numbers and the ecosystem would begin to run out of resources needed to keep the inhabitants alive.

Carrying Capacity

Natural Resources

Renewable Resources

NonRenewable Resources

Polution

Non Point Source

This is pollution that comes from places and things we cannot control.

Organic Pollutant

Pollutants that were living

Water Pollution

Inpermeable

Erosion

Water Purification, Desalination, Aquifer

Runoff

Urbanization

Inorganic Pollutant

These pollutants reach the water the same way as organic matter but inorganic pollutants include fertilizer, detergents, and other excess chemicals.

Point Source

Point source pollution is pollution that comes directly from a source. For example if a factory is dumping waste directly into a river they can be blamed for it and sent to court. This is point source pollution.

Organisms

Any living thing.

Indicator Species

Any animal or species that can define an environment or the environments conditions.

Endangered Species

A species of animal who's population is dangerously low to zero. These animals are taken into custody to be sure they survive.

Threatened Species

Any animal or species that is in danger of being exstict in the future.

Pioneer Species

Groups of plants and animals that begin to live on land that has not been settled before.
