diversity and adaptation of organisms

Adaptations are favourable, heritable variations or changes that enable an organism to increase its chances of survival. Such variations are the result of genetic recombinations or mutation..

It refers to the variation of genes within a species. The genetic diversity enables a population to adapt to its environment and to respond to natural selection. The amount of genetic variation is the basis of speciation. Genetic diversity within a species often increa..

Among the members of the animal kingdom, about 95% do not posses a backbone (or vertebral column) and hence are described as invertebrates. The remaining animals represent a group called chordates, which posses a solid supporting structure on the dorsal side of the body called notochord, at some st..

Every organism whether plant or animal is unique in itself. There is a wide diversity in the flora (plants) and fauna (animals) in the world. The diversity we see today is the result of 3.5 billion years of organic evolutio..

The numerical strength and biomass of organisms affect the functioning of ecosystem. In ecosystems, the biotic communities usually contain a few common species represented by a large number of individuals or by a large biomass and a comparatively large number of individual species occurr..

Habitat is the term given to the special environment in which an organism lives and grows. In order to survive, plants and animals develop special features called adaptive characters that help them to adjust to a particular habitat. This is known as adaptation..
