Example: Most of Pennsylvania
Example: The Boreal Forest
Example: The Arabian Desert
Example: The Arctic Tundra
Example: A Marsh
Example: The Pacific Ocean
Desalinization, Water Purification
Example: Half of Africa

A place where all biotic and abiotic things interact
Non-living things that have never lived, never will live, and aren't a part of a living thing.
Living things, also things that will live or once have, and a part of something living.
The variety of organisms in a geographic area.
A region with extremely high biodiversity.
The process in which the communities of an ecosystem change over time.
The growth of life creating a new ecosystem where there never was one before.
The growth of life creating a new ecosystem where there was one before, but it was destroyed because of one thing or another.
How much a population has increased or decreased.
How many births there are compared to deaths, determining how many new lives or less lives there are per a certain time.
The explosion of sudden growth after a period of consistently staying at the same number.
Species that are vulnerable to endangerement in the near future.
Species vulnerable to extinction in the near future.
Patterns indicating certain things on a graph.
Pollution that can be traced directly to its source, and runs directly to a stream, lake, or river.
Pollution that cannot be traced directly to its source, and doesn't go directly to a river, stream, or lake.
Examples: Detergents, disinfectants, food processing wastes, insecticides, herbicides, petroleum and oil by-products, tree and brush debris, and chemical compounds from personal hygeine and cosmetic products.
Examples: Acidity caused by industrial discharge, ammonia, fertilizers, heavy metals from cars and drainage from acid mining, and sediment from projects.
A surface that does not absorb water or allow it in, causing it to run off. Impermeable surfaces collect litter, gas, debris, etc. which gets washed into our lakes, streams, and rivers.
Water that falls on an impermeable surface and collects everything on it. It goes into streams, lakes, and rivers.
This affects watersheds in many ways. Example: more impermeable surfaces create more runoff that is polluted.
Materials or things that people use from the earth.
Any materials or energy source that cycles or can be replaced during a human life span.
Any material or energy source that cannot be replaced within a human life span.
