Occurs slowly, requires pioneer species, nothing previously there or previous ecosystem completely wiped out from a major disaster

• Primary Succession

• Secondary Succession

Faster, soils undisturbed, same (or similar) climax community

• Primary Succession

• Secondary Succession

Select the example of Secondary Succession

• A forest grows back after a fire destroys old/weak vegetation, soils undisturbed (ashes actually add nutrients to the soil).

• A meteorite vaporizes an entire ocean, a desert forms in its place.

• An area is uncovered by a retreating glacier, allowing for a new ecosystem to form.

• A volcanic eruption covers an entire grassland in many feet of lava, which hardens into stone.

The first organisms to settle a new area

• Pioneer Species

• Primary Consumer

• Secondary Consumer

• Tertiary Consumer

Many different species living in the same area.

• Population

• Community

• Biome
