The name of organisms like plants that form the base of food chains.
What are producers?
500

A forest fire destroys most vegetation but leaves the soil intact. What ecological process is likely to occur next?

What is secondary succession?

500

This process occurs when gases in the atmosphere absorb and re-radiate heat, leading to warmer global temperatures.
