3. Ecosystem diversity:- Ecosystem diversity refers to the range of life forms in a given terrain or locale and the ecological processes that make them function. Ecosystem diversity is often evaluated through measures of the diversity of the constituent species, the relative abundance of different species as well as contemplation of the type of species. Ecosystem is the amalgamation of communities of living things with the physical environment in which they live. Ecosystem diversity is the array of biological communities, such as forests, deserts, grasslands and streams that interact with one another and with their physical and chemical (nonliving) environments. Each ecosystem provides much different kind of habitat or living places providing…show more content…
A functioning forest ecosystem, for example, exhibits rates of plant production, carbon storage and nutrient cycling that are characteristic of most forests. Ecosystem performance reflects the supportive life activities of plants, animals and microbes that affect these activities in feeding, growing, moving, excreting waste, etc. which have on the physical and chemical conditions of their environment. Ecosystem functioning, in turn, is quantified by measuring the magnitudes and dynamics of ecosystem processes (V. Anburaja, 2011). Environmental disturbance on a variability of temporal and spatial scales can affect the species richness and consequently, the diversity of an ecosystem (Mc Dowall, 1996). Ecosystem may be classified according to the dominant type of environment, or dominant type of species present because temperature is an important factor in shaping ecosystem diversity and classification (Udvardy,…show more content…
To human beings, it opens avenues for understanding the laws and ways of nature and for making the optimum sustainable use of life support systems gifted to man by nature. The regulation of biogeochemical cycles, maintenance of predator-prey relationships by various types of food chains and food webs and finally the balance of nature are maintained through biodiversity. Again it indirectly influences the climatic factors, soil nature, chemistry of air etc. that are the abiotic elements of an ecosystem. Ecosystem diversity could be best understood if one studies the communities in various ecological niches within the given ecosystem. Community diversity: Habitats can be defined as areas that provide the resources requirements for a discrete phase of a plant or animal’s life (Southwood, 1981) It’s often difficult to define boundaries for habitats and there are clear problems in defining when one habitat becomes another between species is another ecological value, again hard to measure. This related to the complexity and possibly the stability of an ecosystem (Tocharntke, 1992) Classification of natural ecosystems into potential plant communities and habitat types is important for the long term management of natural resources. Ecologists always try to understand the variation in species diversity along the environmental gradient like altitudinal gradient in mountainous ecosystems (Daubenmire, 1968; Vetaas & Grytnes,
