Succession that occurs in an area with NO SOIL

• ecological succession 
• primary succession 
• secondary succession
• pioneer speciles

Why does primary succession typically occur over a longer period of time (as compared to secondary succession)?

• Because trees do not perform respiration

• Because the climax community is usually a forest.

• Because primary succession already has soil

• Because primary succession does not begin with soil being present

What is an succession?

• Series of gradual changes that occur after a disturbance
• Changes that only happen when species die
• a series of changes that cause a population to increase or decrease
