A group of individuals of a particular species occupying a particular area at specific time is called as population. A species is a group of similar type of organisms that can interbreed under natural conditions. The interbreeding organisms of a species produce new organisms and finally result into the growth of population. This is true for all the life forms including human beings.
A forest is a highly complex and constantly changing environment. It is made up of a variety of living things like wildlife, trees, shrubs, wildflowers, ferns, mosses, lichens, fungi and microscopic soil organisms; and non-living things such as water, nutrients, rocks, sunlight and air. Trees are the biggest part of this complex community.
The biosphere is itself a vast ecosystem which incorporates all the small ecosystems. But, the biosphere may have different types of physical conditions, communities of plants and animals, and climatic conditions in its different zones.

Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
The year 2022 has remained a year of big scientific achievements. In it, the discovery of probability of wormhole and Dart campaign of NASA in space science have been remarkable.
