Use the passage to answer the question.
Most forest fires and wildfires are natural. They clear away debris, old brush, and dying trees, leaving heartier trees better able to grow. Certain trees, in fact, produce seeds only when fire heats them. If the fire removes thick shrubs and undergrowth, the water supply increases, aiding other plants and local animals.
