Limiting factors

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

Succession: changes over time

Primary succession Takes place on land where there

are no living organisms

Succession: changes over time Secondary succession

The sequence of changes that take place after an existing community is disrupted in some way

Ex: forest fires, volcanoes, hurricanes, etc

Biomes

Major geographic communities with similar climates and vegetation

Aquatic biomes

Photic zone = the portion that is shallow enough for light to penetrate

Ex: intertidal zones, estuaries, coral reefs

Aquatic biomes

Aphotic zones = deeper waters that never receives sunlight

Ex: the abyss
