which three sentences describe how a wildfire can harm a forest
ecosystem?
Answer:
The wildfires can damage forests that remove carbon dioxide. The wildfires also emit carbon dioxide, and these damaged trees do not have the strength to remove the carbon dioxide from the air. So this causes well-known global warming, which is a bad sign and is harmful to the atmosphere. And on top of that, the wildfires inject soot and aerosols into the air, causing quite complicated effects on the environment's ability to warm and cool on a regular basis.
Wildfires can ruin not just forests, but our world.
