Question

6. How do fires help to renew the grasslands?
7. What are conifers?
8. Describe how some animals and birds of the temperate zone behave in winter.​

Answer 1

Answer:

Forest fires are a natural and necessary part of the ecosystem. Even healthy forests contain dead trees and decaying plant matter; when a fire turns them to ashes, nutrients return to the soil instead of remaining captive in old vegetation.

Answer 2

Explanation:

Fire is a natural part of the grassland ecosystem and helps maintain its health and vigor. It warms up the soil and reduces the leaf litter that accumulates each year, allowing sunlight to penetrate .

Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta, also known as Coniferophyta or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth.

Some animals of the temperate zone hibernate during the winter. This means that they go into a deep sleep and only wake up once spring comes. Other animals, particularly birds, migrate to warmer places as winter approaches. They return to the temperate regions once spring comes.
