Forests are lifeline of our planet Earth, as they provide fresh and pure oxygen rich air and pure water for our living. A forest consists of several different types of herbs, shrubs, climbers, creepers and trees with branches spread out widely. Such branches are called as crown of the tree. Trees with wide branches planted in a row, provide a roof-like structure, called as canopy. These canopies prevent the sunlight and make the atmosphere dark and cool. The soil of the forest is rich in minerals, thus offering the growth of diverse plants. There are many trees which are as old as 100-200 years. It is nature which enables the germination of seeds and saplings in the forest over a period of time. Some areas of forests have understoreys, that is layer of giant trees, followed by tall trees and then by shrubs and herbs. The plants and animals present in forests vary depending on the climatic and environmental conditions. Forests rich in nutrients:

There are several insects and dead, decaying leaves also present in the forest. Sometimes, when an animal dies, scavengers like vultures and wolf prey on dead animals and leave the remaining to be decomposed by other organisms. Some insects and micro-organisms eat up the dead and decaying matter and convert it into black-colored substance called humus. Such organisms are known as decomposers and play a role in providing the soil with natural compost. Hence, there is no wastage in a forest. Green lungs:

Forests are also known as green lungs, as they maintain a perfect balance between oxygen and carbon dioxide. Oxygen is created by photosynthesis process and used up by animals which exhale carbon dioxide into the air. In addition, trees of the forest also contribute greatly to the water cycle. Fewer trees would affect the water vapor content released into air, which in turn would affect cloud formation and the pouring of rains further. Forests provide basic needs:

Forests are home to plants, animals and several...
