Ch 4 - Succesion, Biomes, Aquatic Ecosystems

Succession

100

THIS type of succession begins on bare rock

Primary succession

200

THIS type of succession can occur relatively quickly

Secondary Succession

300

This would most likely occur after a lava flow

Primary Succession

400

These are the first organisms to repopulate an area affected by a volcanic eruption

Pioneer Species

500

THIS is a disturbance from which a community might not recover on its own and rebuild the original climax community.

Human disturbances: strip mining, pollution, oil spills, etc

Terrestrial Biomes

100

This area is not classified into a biome but is cold year round.

Polar Ice caps

200

These tall landforms are not classified into a major biome

Mountains

300

These are two factors that determine which biome an area is.

Temperature, precipitation, soil, sunlight, lattitude, etc

400

The biome WE live in.

Temperate Forest

500

This biome is warm year-round, has seasonal rainfall and grasses that grow from their bases. Many grazing herbivores would be found here.

Tropical Grassland/Savannah

Aquatic Ecosystems

100

You are NOT likely to find phytoplankton or algae in THIS aquatic zone

Aphotic

200

A wetland that contains a mixture of fresh water and salt water that is important for the reproduction of many fish and shellfish species.

Estuary

300

These are the four factors that affect aquatic ecosystems.

temperature, depth, nutrient availability, currents

400

Barnacles and seaweed can be found living in THIS marine ecosystem, which is submerged in saltwater at high tide and exposed to air and sunlight at low tide

Intertidal zone

500

The 4 zones of marine ecosystems are determined by THESE 2 criteria

Depth & Distance from shore
