In temperate forests, coarse woody debris—such as fallen trees and decaying branches—plays a critical role in maintaining a healthy ecosystem. Although these rotting logs may look like waste, they provide essential shelter and nesting sites for a wide range of forest creatures, including insects, birds, and small mammals. Furthermore, as the wood decays, it slowly releases vital nutrients back into the soil, fertilizing the surrounding plants. Because of these ecological benefits, modern forest managers often choose to leave fallen timber on the forest floor rather than removing it.
Which choice best states the main idea of the text?
- AForest managers prefer to clear away fallen timber to help new plants receive more sunlight.
- BInsects, birds, and small mammals are the only animals capable of building nests in decaying logs.
- Fallen and decaying wood benefits forest ecosystems by providing shelter for wildlife and nutrients for the soil.Answer
- DAll organisms in temperate forests depend entirely on coarse woody debris to survive.
Answer
Fallen and decaying wood benefits forest ecosystems by providing shelter for wildlife and nutrients for the soil.
The correct answer accurately summarizes the main point of the passage, which explains how decaying wood supports the forest ecosystem by providing habitat for animals and returning nutrients to the soil.
