Biology Review

In an ecosystem, there are populations of moose, 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

• Secondary succession

• Tertiary succession

• None of the above
