Which type of succession is a process that brings life into a previously uninhabited area?
cyclic succession
seasonal succession
secondary succession
primary succession
What type of succession is likely to occur immediately following a tsunami that caused significant soil erosion?
secondary succession because all the soil was lost in the tsunami
secondary succession because some soil will still be left behind after the tsunami
primary succession because the tsunami killed so many organisms in this ecosystem
primary succession because there were still some organisms that survived to recover the ecosystem
How do mosses and lichens most contribute to succession?
They are producers in the food chain.
They break down rock into soil.
They increase the amount of oxygen in the surrounding air.
They become plants.

True
False
What is ecological succession?
gradual change in living communities that follows a disturbance
rapid change in a nonliving community
a change that occurs in a community overnight
how an ecosystem is changed into livable land for humans
Primary Succession starts with

land that was previously inhabited
already has soil
a clear cut piece of land
