​What is pioneer species? Why it is important?Pioneer species-Stages Primary Succession | Ecology Basics| - YouTube

Multiple Choice

The development of an ecosystem in an area that has been covered by lava begins with the

• breakdown of rock by pioneer species.

• migration of animals.

• growth of trees and shrubs.

• appearance of soil.

Multiple Choice

Lichens and mosses that first live in uninhabited areas are examples of

• non-native species.

• pioneer species.

• primary species.

• secondary species.

​Why does secondary succession take less time?

Multiple Choice

Secondary succession is most likely to occur

• after a forest fire.

• with pioneer species.

• if a glacier shrinks.

• on a new volcanic island.

​A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference.
