Question

Most forest fires and wildfires are natural. They clear away debris, old brush, and dying trees, leaving heartier trees better able to grow. In fact, some trees only produce seeds when heated by fire. If a wildfire removes thick shrubs and undergrowth, the water supply increases, which helps other plants and local animals. Fire may also kill predatory insects or pests that live on and damage otherwise healthy trees.

In two sentences, identify the main idea and at least one supporting detail of this paragraph.

Answer 1

The main idea of this paragraph is that most forest fires and wildfires are natural and beneficial to the ecosystem. One supporting detail is that fires clear away debris, old brush, and dying trees, allowing heartier trees to grow.
