The day-to-day conditions
Described in terms of months at a time
B and C are both correct
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
None of the above
