Biology is related to various other branches of science. Biology is not a single science but is a science of sciences. In fact all disciplines of science are interrelated and interdependent. The study of biology has gone so vast and deep and to cover its wide scope, today a new name ‘life science’ is used in place of biology. “The branch of science which deal with study of living beings is called life science”.

Life is due to continuous process of chemical reactions of the body. If we want to know how a plant manufactures food or how blood clots, we need to use our knowledge of chemistry. The functioning of the eye especially the formation of image or the conduction of water from roots to the higher parts of the plants can be best understood only by applying our knowledge of physics. New branches of sciences such as biochemistry and biophysics have arisen which deal with the application of chemistry and physics to biological problems. The study of geology, geography, astronomy, meteorology, oceanography, physiography is also essential for understanding the knowledge of physical environment.

Biodiversity 

Biodiversity or diversity in the living world is the occurrence of a wide variety of life forms differing in habitat, habits, size, morphology, colour and anatomy. Each diverse from plants, animals or microorganism represent a species. The word biodiversity was first used by Walter G. Rose in 1986 for different types and diversity of plants, animals and microbes. Thus, Biodiversity is the richness of species of all organisms like plants, animals and microbes that arises in a habitat as mutually interacting system.

Everywhere we look around, we see life in a incredible variety.
In other words, life around us in immensely diverse. There are more than 10 million kinds of plants and animals reported on the earth today. At present approximately 1 million species plants and animals have been named. Out of these insects from the largest group. Some other groups are Protozoa (30,000 species), Cnidaria (9,000 species); Arthropoda (80,000 species), chordate (65,000 species), etc. all the living beings constitute the “Living world”. According to the estimate about 10,00,000 species of animals and 5,00,000 species of plants have been discovered so far. The plants and animals are the parts of the living world. 

The member of the living world show variations in their habit, habitat, size, external appearance, etc. On the one hand we come across Chlamydomonas, Amoeba like minute living beings which can seen through the microscope, Whereas on the other hand we come across giant tress and blue whale, the latter is the largest known animal in the living world.
