There are various uses of Solar Energy. Farmers in Traditional Farming Communities used to solarise fields by living them empty after a deep ploughing during summers. It killed insects and pests. Human skin synthesizes vitamin-D when exposed to sunlight for short durations. Mothers used to make their babies sleep in the sun after oiling their bodies during winters in order to keep them healthy and strong.
Anything from which we can derive energy is called as a source of energy. Since all the life processes need energy, energy is most important for our survival. Our body derives energy from the food we eat. Thus, the food we eat is the source of energy for our body. But this is not the whole story. We need energy for our growth and economic development as well.

Consumers too utilize some energy in their metabolic processes. Under these conditions some energy escapes away in the form of their body heat and some energy is wasted through excretory matter from their bodies. The rest of the energy goes into the atmosphere when top consumer dies and its body is decomposed.
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.
The Wind is Air in Motion. It is caused by differential heating of land, water, hills and mountain slopes by sun rays. About 25 % (i.e., 0.34 KW/m2) of incident solar radiation is dissipated as wind energy. There is kinetic energy in wind.
Sun is the only source of energy in the biosphere. Every living being can get its share of energy through food only and the energy is directly or indirectly obtained from green plants only.
Energy is the basic force capable of running life. But, the sources of energy are running short.
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.
Interdependence between two species through which individuals of either one or both species benefit is called positive interdependence. The benefits to the individual of any species through this relationship may be continuous or transitory, obligate or facultative. Both partners in this type of relationship may be in close contact; one may be inside some specific area or attached to the surface of the other’s body. Positive interdependence is divided into three major types: mutualism, Commensalism, and proto-cooperation.
