1

Community

Group of interacting populations that occupy the same area at the same time

2

Limiting Factor

Any abiotic or biotic factor that restricts the numbers, reproduction, or distribution of organisms

3

Tolerance

The ability of any organism to survive when subjected to abiotic factors or biotic factors

4

Ecological Succession

The change in an ecosystem that happens when one community replaces another as a result of changing abiotic and biotic factors

5

Primary Succession

The establishment of a community in an area of exposed rock that does not have any topsoil

6

Climax Community

The stable, mature community that results when there is little change in the composition of species

7

Secondary Succession

The orderly and predictable change that take place after a community of organisms has been removed but the soil has remained intact

8

Weather

The condition of the atmosphere at a specific place and time

9

Latitude

The distance of any point on the surface of Earth north or south of the equator

10

Climate

The average weather conditions in an area, including temperature and precipitation

Plankton

Free-floating photosynthetic autotrophs that live in freshwater or marine ecosystems

23

Profundal Zone

Deepest areas of a large lake

24

Wetlands

Areas of land such as marshes, swamps, and boggs that are saturated with water and that support aquatic plants

25

Estuary

An ecosystem that is formed where freshwater from a river or stream merges with salt water from the ocean

26

Intertidal Zone

A narrow band where the ocean meets land

27

Photic Zone

Open-ocean zone shallow enough for sunlight to penetrate

28

Aphotic Zone

Open-ocean zone through which sunlight cannot penetrate

29

Benthic Zone

Ocean-floor area consisting of sand, silt, and dead organisms

30

Abyssal Zone
