Environmental Science: Brianna


A living thing.


Geographic area with many ecosystems, based on climatre.  

Temperate deciduous forest

Example: Most of Pennsylvania

Coniferous forest

Example: The Boreal Forest


Example: The Arabian Desert


Example: The Arctic Tundra


Example: A Marsh


Example: The Pacific Ocean


Example: Half of Africa


Example: The Amazon Rainforest

Food Chain

Trophic Levels

Food Web


A place where all biotic and abiotic things interact

Abiotic Factors

Non-living things that have never lived, never will live, and aren't a part of a living thing.

Biotic Factors

Living things, also things that  will live or once have, and a part of something living.


The variety of organisms in a geographic area.

Species Biodiversity

Genetic Biodiversity

Ecosystem Biodiversity

Hot Spots

A region with extremely high biodiversity.

Ecological Succession

The process in which the communities of an ecosystem change over time.

Primary Succession

The growth of life creating a new ecosystem where there never was one before.

Secondary Succession

The growth of life creating a new ecosystem where there was one before, but it was destroyed because of one thing or another.



Population Growth

How much a population has increased or decreased.

Population Growth Rate

How many births there are compared to deaths, determining how many new lives or less lives there are per a certain time.

Exponential Growth

The explosion of sudden growth after a period of consistently staying at the same number.

Limiting Factors

Carrying Capacity



Threatened Species

Species that are vulnerable to endangerement in the near future.

Endangered Species

Species vulnerable to extinction in the near future.

Indicator Species


Patterns indicating certain things on a graph.



Water Pollution

Point Source

Pollution that can be traced directly to its source, and runs directly to a stream, lake, or river.

Non-Point Source

Pollution that cannot be traced directly to its source, and doesn't go directly to a river, stream, or lake.

Organic Pollutant

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.

Inorganic Pollutant

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.


Natural Resources

Materials or things that people use from the earth.

Renewable Resources

Any materials or energy source that cycles or can be replaced during a human life span.

Nonrenewable Resources

Any material or energy source that cannot be replaced within a human life span.
