Sometimes, if a particular species is absent in a particular area, that species is replaced by another species so that the “to eat and to be eaten” system will be maintained. For example, in a grassland ecosystem, if frogs will remain constant…
The transfer of food energy from the source in plants through a series of organisms with repeated eating and being eaten is referred to or called as food chain. The green plants are the autotrophs or the producer of the ecosystem. With the help of chlorophyll, and by using CO2 and H2O from nature in…
Ecological succession term was coined by Hult (1885). Famous ecologist Clement defined Ecological Succession as “the natural process by which the same locality becomes successively colonised by different groups or communities of plants”. Characteristics of Ecological Succession The species types and the community changes in an orderly process The physical structure of a community changes…
The study of all the physical as well as biological processes including the distribution and abundance of living organisms and the interaction in between them with their surrounding environment is known as Ecosystem. In simpler words, if any environmental changes occur in the physical or abiotic factors, they in turn change the type and number…
It was the global perception that the environmental conservation and economic development cannot be pursued together.

Multidisciplinary means interaction of various subjects or disciplines. Environmental studies deal with all the aspects of biotic and abiotic components of the environment. Also, Environment and environmental issues are complex in nature. Therefore, expertise from different subjects or disciplines is required to understand different aspects of the environment. We may require expertise from different disciplines…
