Hello,

Forests, particularly trees are considered as backbone of ecosystem and nature. Forests purify and filter the air by taking harmful gases and releasing fresh oxygen. Forests also attracts cloud and are a major cause of rains. All the animals depend on Forests directly or indirectly because forest are on the producer level of food chains. All herbivore depend on forest for food and survival  and other meat eating indirectly depend on forest for survival as they eat the herbivore. Forest also reduce soil erosion by binding the soils to the roots of trees.

For Example - Sundarban forest (Famous for White Bengal Tiger) is home of many species. Herbivore of this forest depend on trees and plants for food. Other carnivore and omnivore depend on these herbivore. So, directly or indirectly all the habitat of an ecosystem depend on Forest. Because of Trees this forest have frequent rains also.

Hope this was helpful.

Hello

Forests are the sources of many things like products.. example, wood, fruits etc

Apart from that from the ecology point of view, forests support to a greater extent in maintaining climate and reducing global warming by

1. Rains.. Due to them, temperate is in control and rain fall occurs

2. Soil erosion control... Due to the floods, many places experience soil erosion. Since forests and trees are there, soil erosion is controlled

3. Regulating carbon dioxide... they take in all the carbon dioxide which we leave and there by pollution and global warming is in control

4. Natural habitat for many animals which helps is stabilizing the ecological cycle
