Primary and secondary succession

By Ethan le

Primary succession

Primary succession is when new life grows on newly formed land which nothing has grown on like a volcanic rock after an eruption. It takes 1000 years to reach climax community. After the eruption lichens and mosses grow (To the right).

After lichens and mosses

After the lichens and mosses ,the nutrients of the dead plant and the soil it made is left behind. Then shrubs, herbs, and small bushes grow.

Secondary succession

After primary succession

There is a forest fire or tornado that clears out the land. Then Secondary succession takes it's roll. Secondary succession is when a natural disaster strikes and the plants grow off the nutrients in the ashes and soil. It takes 100 years to reach climax community. Then annual plants grow (to the right).
