How is secondary succession different from primary succession?

• Occurs after a disturbance in a previously uninhabited area

• Occurs after a disturbance in an area where the soil remains intact

• Occurs over a longer period of time

• Occurs when animals are introduced to an area

How do pioneer species make ecological succession possible following a volcanic eruption?

• They use chemicals to produce food.

• They establish homes in which animals can live.

• They break down rock into soil in which plants can grow.

• They adjust the climate by altering the average temperature
