Primary succession is...

• When a hurricane causes a river to flood its banks

• When a farmer ploughs his fields to remove all existing plant life.

• When fire burns through a forest and ills all vegetation less than 1m tall.

The secondary succession is

• lichens and mosses arrive on bare rock and begin to trap soil

• a complex, stable ecosystem is formed

• plants grow in an area devastated by a flood

• plants grow in a newly formed pond
