Question

What is biomass? What can be done to obtain bio-energy using biomass?

Answer 1

Hint: There are many kinds of sources of energy. One of them is biomass. Biomass is a renewable source of energy. It is formed from plants and animals. The energy obtained from the biomass is called bio energy.

Complete step by step answer:
One of the renewable and conventional sources of energy is biomass.
Biomass is renewable material that is formed from the remains of the dead plants and animals. Biomass is also formed due to organic materials. Some of the organic materials are crop manure, animal waste, firewood and human waste. Biomass can be dry as well as wet.
Biomass is a renewable source of energy. The energy obtained from the biomass is called bio energy. Biomass is used to generate heat. It is said that biomass stores sunlight in the form of chemical energy.
One of the ways to obtain bio energy from biomass is to burn the dry biomass directly.
Another way is to convert the biomass into biogas. Biogas is the gaseous form of biomass. It is produced when the biomass undergoes anaerobic fermentation in the presence of water.
The biogas is used as a fuel for producing the bio energy.

Note: Let us discuss how biomass is considered as a renewable source of energy.
Biomass is considered as a renewable source of energy because its energy comes from the sun and it can regrow in a very short time.
Biomass is obtained from photosynthesis. Hence, it is available until we have plants and trees.
