Because biological energy transformations are inefficient, a substantial proportion of metabolized food energy is lost, unused, as heat. Secondary productivity is defined as the rate of formation of new organic matter by heterotrophs of the net primary productivity available in a forest, herbivores e.
Primarily inland, fresh water habitats are grouped into two categories: Abiotic Components These are the nutrients present in soil and the aerial environment. There is a very rich floristic and faunistic composition due to moderate temperature, high humidity, better soil nutrient and moisture regime.

Primary productivity in ecosystems depends on the uptake of essential mineral inorganic nutrients by plants and their incorporation into living tissues.
There are two basic types of systems: Shallowness of the water allows the development of a large biomass of lightly productive rooted aquatic plants. The green plants prepare food by using radiant energy and transform them to chemical energy.
Excess quantity of minerals however may be toxic to the life forms. However, natural systems are rarely so orderly and linear.
