In some national parks, controlled fires are maintained by firefighters. Which of these is one of the major reasons for using controlled burns to maintain certain ecosystems? to allow the spread of insects that provide food for animals to rid the forest floor of accumulated deadwood and brush to give nonnative plants a chance to colonize the region to replace mature plants with saplings of the same species

Why is regular burning (thru natural fires) an important part of maintaining the health of grasslands and coniferous forests? Identify benefits that are specific to each biome. Also, discuss how suppressing fires could negatively affect each system.

In 1988, wildfires swept through nearly 800,000 acres of Yellowstone National Park. The fire killed many of the trees and shrubs, leaving vast swaths of land without plants. This left the burned area open for new plant colonization. Forest fires also tend to release large amounts of nutrients to the soil. Within a few years, some species of plants, such as fireweed, experienced exponential growth in the burned area. Which of the following environmental factors likely led to the exponential growth seen in fireweed after the Yellowstone wildfires? decrease in competition from other plants increase in nutrients increase in predation from insects increase in sunlight increase in habitat
