a) Specific;

Decomposers (like bacteria and fungi) work only on dead and decaying matter to obtain nutrients from them.

b) Producer;

Green plants have chlorophyll and they use energy from sun, water and carbon dioxide to make their own food, so they are called producers. Animals are consumers because they cannot make their own food. They either eat plants or other animals.

c) Food chain;

Food chain can be defined as a series of organisms where each organism is dependent on the next for food.

d) Ecology;

Ecology is the study of how organisms interact with each other and their environment.

e) Non-biodegradable; biodegradable.

Plastic is non-biodegradable because it is rarely consumed by bacteria so they do not decompose. Whereas, paper is biodegradable because paper is made of plant material and plant materials are biodegradable.
