Which of the following are true?

• None of the responses are true

• Primary succession begins in an area that does not have soil.

• Primary succession occurs in an area that already had life and soil.

The first species to appears are lichens, then mosses and then (a)  

After grasses and flowers arrive, then bushes and shrubs, and finally (a)  

Lichens are often the first species to colonize an environment during primary succession. What is the name of the first species to colonize an area?

• primary succession

• a pioneer species

• secondary succession

• a first order consumer

How do lichens change the abiotic (non-living) environment to help other species of plants?

• They provide energy for other plants

• They reflect sunlight to help them grow

• They break down rock and form soil

• They are a good food source for pollinators
