2.1. Ecosystem
A community or a series of communities and the surrounding physical and chemical environment together constitutes an ‘ecosystem’. An ecosystem is a dynamic entity composed of a biological community associated with abiotic environment. The dynamic interactions that occur within an ecosystem are numerous and complex. Ecosystems are always undergoing alterations to their biotic and abiotic components. The most obvious impact of humans on ecosystems is the loss of biodiversity.
