Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common goals. In the living system, we can see..

Each link in a food chain is known as a trophic level. For example, in each food chain, plants always form the first trophic level. The plant eating animals called herbivores like insects, rodents, rabbits, deer, cattle, etc. form the second trophi..

Human Dependence on Plants and Animals for Food - Of all the living organisms, only plants are autotrophs i.e., they are capable of synthesizing their own food. Animals are heterotrophs i.e. they are incapable of synthesizing their own food. They depend on ..

Need for Preservation - Plants and animals occupy diverse habitats. It becomes practically impossible for a biologist to study each and every plant or animal species in its natural habitat. Hence, over the years attempts have been made to preserve the pl..
