Question

Which describes a situation in which a forest fire can be helpful to an ecosystem?

A. they destroy diseases and harmful insects that may have been infecting an area
B. they cut down on the numbers of different animal species living in a forest
C. they burn dead inorganic matter and return the nutrients to the soil.
D. they destroy many plants growing on the forest floor allowing older plants life to continue to grow.

Answer 1

C is the correct answer. Nothing good comes from cutting down animal species, and nothing good comes from allowing older plants to grow either. Releasing nutrients back to the soil allows the ecosystem to continue and grow.

Answer 2

C. they burn dead inorganic matter and return the nutrients to the soil.

Hope this helps!
