Study the series of pictures above. Which description below best describes what is happening in the pictures?

• A) Secondary succession is occurring because there is a fire in an area where organisms already lived and in picture 5 the plants are beginning to re-grow.

• B) Secondary succession is occurring because there are large plants (trees) and secondary plants (grasses) in the same community.

• C) Primary succession is occurring in the pictures because in picture 4 the community is all the way down to the soil so it must begin growth all over again.
