In the woods, there are ducks and mice. They both compete for grasshoppers as the only source of food in that area at that time. The ducks outcompete the mice, and the mice die out in that area. This is an example of:

• Neutralism

• Commensalism

• The competitive exclusion principle

• Mutualism

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.

• Primary succession

• Secondary succession

• Tertiary succession
