AP Bio Population Ecology

In an ecosystem, there are populations of deer, rabbits, grass, and pine trees. Suddenly, a fire blazes through the area, which kills all of the populations. As the months go on, new species of grass begin to take root. This attracts animals, and eventually the ecosystem is restored.

What type of ecological succession happened?

• Primary succession because it started with rocks.

• Primary succession because there was soil to begin with, and plants existed before the disaster.

• Secondary succession because it started with rocks.

• Secondary succession because there was soil to begin with, and plants existed before the disaster.
