A good source of energy satisfies: It does a huge amount of work per unit mass. It is easily accessible. It is easy to store and transport. It is economical.
Non-biodegradable substances do not decompose easily so it produces land and water pollution. These substances can harm animals, human and can even cause their death if eaten accidentally.

The microorganism like bacteria and other decomposer organisms (called saprophytes) present In our environment are specific in their action. They break down the materials or products made from natural materials (say, paper) but do not break down man-made materials such as plastics. So, it is due toRead more

saprophytes) present In our environment are specific in their action. They break down
the materials or products made from natural materials (say, paper) but do not break
down man-made materials such as plastics. So, it is due to the property of decomposer
organisms of being specific in their action that some waste materials are biodegradable,
whereas others are non-biodegradable.
(i) Decomposers help in decomposing the dead bodies of plants and animals and hence act as cleansing agents of the environment. (ii) Decomposers also help in putting back the various elements of which dead plants and animals are made, back into the soil, air and water for reuse by the producers likeRead more
