Detailed explanation-1: -After a major forest fire kills all of the plants in an area, the first plants to grow in the burned area are often types of grass. Because they are the first thing to grow in the new ecosystem, these types of grass are called pioneer species.

Detailed explanation-2: -Imagine a forest that has been destroyed by a forest fire. All the plants and animals that lived there are gone. But the burned-up forest will not remain lifeless forever. Plants and animals will return to the area in a process called ecological succession.

Detailed explanation-3: -Annual plant life, such as weeds and wildflowers, are the first species to return to a disturbed habitat. They sprout from seeds during the first year or two after the fire. These pioneer plants help transform the mineral composition of the soil, making it more hospitable.
