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.
All those processes that maintain the body of an organism collectively are called as life processes. These processes principally include Nutrition, Respiration, Internal Transport, and Excretion. Some other processes of life like control and coordination, Reproduction, Heredity and Evolution etc. are essentially found in living beings but they are not directly related to processes of life. Hence, these may or may not be regarded as life processes
The dry weight of organic matter produced by plants, their derivatives and wastes are called as BIOMASS. The biomass includes crop residues, plant parts, body parts of dead animals and animal wastes. As biomass is created due to photosynthesis by plants, so energy from biomass or bio wastes is regarded as another form of solar energy.
