Question

why have forest fires in ponderosa pine forests become more damaging to that ecosystem than they were historically?
a. following a policy of fire suppression in these forests makes fires burn hotter.
b. fires in ponderosa pine forests are generally low - intensity fires.
c. following a policy of fire suppression in these forests clears out underbrush..
d. forest fires are a natural part of ponderosa pines forest ecosystems.
please select the best answer from the choices provided
a
b
c
d

Explanation:

Historically, ponderosa pine forests had frequent, low-intensity fires that cleared small amounts of underbrush. Fire suppression policies stopped these natural fires, allowing dense underbrush and small trees to accumulate. When fires do occur now, this excess fuel makes them burn much hotter and more intensely, causing far more ecosystem damage than historical fires. Option B describes historical fires, not the current damaging ones. Option C is incorrect because fire suppression builds up underbrush, not clears it. Option D is a true statement but does not explain why fires are now more damaging.

Answer:

a. Following a policy of fire suppression in these forests makes fires burn hotter.
