Ecological Succession

Group 1

Ecological succession

When the environment structure changes over time

Primary succession

Occurs when rock is uncovered and organisms begin to grow on this land

Slow process because soil is not present in the beginning

Small organisms begin to grow on the rock, like mosses and lichen

When they die, they create soil so that large plants can grow

Diversity begins to increase

Secondary succession

Occurs when am excisting ecosystem is destroyed

This could occur because of a fire, flood, or hurricane

Soil is present so process does not take as long as primary succession
