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. Fire also may kill predatory insects or pests that live on and damage otherwise healthy trees Write two sentences summarizing information in the paragraph.

Answer 1

Wildfires are crucial to maintaining ecosystem health and support species such as the jack pine that require fire for reproduction. They also help control pests and replenish soil nutrients.

Step-by-step explanation:

Forest and wildfires serve as important agents of disturbance in terrestrial ecosystems, clearing debris and promoting the growth of certain species. For example, jack pines require fire to open their seed cones and continue their life cycle. Moreover, fire contributes to ecosystem health by adding nutrients to the soil, increasing water availability, and controlling pests, which supports a diversity of plants and animals.

Answer 2

Forest fires and wildfires are natural because they help to clear debris, old brush, and dying trees. This helps the trees to be able to grow along with the seeds produced when fire heats them.
