Renewable Energy
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.
Biomass Energy and its implications
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.

Animals : domestic and wild
Animals can be categorized mainly into two categories- domestic, and wild. However, the domestic animals that live under wild conditions are called Feral Animals.
Conservation of Wildlife
Conservation of species in their natural habitats- in areas where they occur under normal conditions is called in-situ conservation.
This type of conservation strategy protects the entire area. Such an area is protected and maintained to conserve all the known or unknown species inhabiting it.
In this type of conservation, species are not isolated or provided with health care, food, or mating facilities. Only factors detrimental to species’ existence and development are eliminated in this conservation strategy. Human interference, such as hunting, cutting down trees, collecting firewood, etc., is completely banned in such areas.
Hazardous Waste- Handling and Management
In India, a Hazardous Substances Management Division has been constituted as a nodal point within the Ministry of Environment and Forest. This nodal agency is responsible for Planning, over-seeing and implementing the policies and programmes on management of hazardous substances and Chemical Emergencies.
How does energy flow through an ecosystem?
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.
