All biosphere ecosystems have well-organized functions, such as cycling nutrients through food chains, operating biogeochemical cycles, and maintaining the energy flow received by green plants through solar radiation.
Abrupt changes in environment often do not give time to an organism to get ready and to face the challenges. As such the organism can survive only when it has sufficient abilities to tolerate these changes.

Vast variability exists in the distribution or occurrence of different life forms in different habitats. The variability of life forms in a particular habitat is considered as the biodiversity of that habitat.
The predominant features that create structural complexity in the environment, such as plants or animals are called as a habitat.
A process, in which natural habitat is rendered functionally unable to support the plants and animals occupying it, is named as Habitat destruction. In the process of habitat destruction, plants and animals that previously used the place are displaced or destroyed, reducing biodiversity.
Biodiversity and other sources supply raw materials to many important industries. They have aesthetic value and appeal for ecotourism, which supports the growth of the national economy. They are also potential sources of pharmaceuticals, other chemicals, agricultural materials, etc.
Conservation of species in their natural habitats- in areas where they occur under normal conditions is called in-situ conservation.
This type of conservation strategy protects the entire area. Such an area is protected and maintained to conserve all the known or unknown species inhabiting it.
In this type of conservation, species are not isolated or provided with health care, food, or mating facilities. Only factors detrimental to species’ existence and development are eliminated in this conservation strategy. Human interference, such as hunting, cutting down trees, collecting firewood, etc., is completely banned in such areas.
Roots of plants too, respond to the changes in climate.
