Power of accommodation is the ability of the eye lens to focus near and far objects clearly on the retina by adjusting its focal length. Power of accommodation of the eye is limited. It implies the focal length of the eye lens cannot be reduced beyond certain minimum limit.

Natural gas can be used for heating and cooking food as it is a clean source of energy. It has high calorific value also It does not produce a large amount of smoke on burning. It is easy to use and easy to transport.

A fuel is considered good or desirable when it has a low ignition temperature and generates a significant amount of heat. It reflects it high in its calorific value. Ideal fuels should be easy to store, leaving behind ash after they are burned and quickly combust. They are inexpensive , readily available and do not emit any harmful smell. While burning can be easily carried and can be regulated.
The characteristics of good source of energy are (a) It should have high calorific value. (b) It should be easy to handle. (c) It is should be easily available. (d) It is easy to store. (e) It should be cheaper. (f)It should produce less amount of smoke.

The various links or steps in a food chain at which the transfer of food and energy takes place are called trophic levels.
The producers form the first trophic level as they manufacture food. The primary consumers form the second trophic level, the secondary consumers form the third, and the tertiary consumers form the fourth trophic level.
Grass is the producer which is eaten by the grasshopper known as primary consumer. Then the grasshopper is eaten by shrew, secondary consumer and lastly shrew eaten up by owl, tertiary consumer.
Natural resources of the Earth must be distributed among the people uniformly so that each and every one gets his share of the resource. Human greed, corruption, and the lobby of the rich and powerful are the forces working against an equitable distribution of resources.
