Question

How can fire both benefit and threaten forest ecosystems?

Answer 1

Answer:

Crown fires are extremely hot fires that leap from treetop to tree top burning whole trees. This can destroy more vegetation, kill wildlife, increase soil erosion, and burn/damage human structures in their paths.

Answer 2

A benefit of forest fires is that some types of pine cones from coniferous trees actually open up only when exposed to really hot temperatures, such as those in a forest fire. So after the fire, a new forest is naturally planted. Also, soil is given plenty of nutrients as remains of plants and animals decompose.
