The power of accommodation is the ability of the eye to focus on distant as well as nearby objects by changing the focal length of lens.This focal length of eyes is changed with the help of ciliary muscles.

Natural gas can be used for heating and cooking food because it is a clean source of energy. It does not produce huge amount of smoke on burning. Although it is highly inflammable, it is easy to use, transport, and it produces a huge amount of heat on burning.

A good fuel should have the following characteristics. It should be easily available. It should be cheap. It should have a high calorific value. It should have a low ignition point, which is not lower than room temperature (so that it does not catch fire at room temperature). It should not burn tooRead more

A good source of energy fulfils the following criteria: It produces a lot of heat per unit mass. It does a huge amount of work per unit mass. It is easily accessible. It is easy to store and transport. It is economical. It produces less amount of smoke.

Decomposers break down complex organic substances into simpler substances.Since decomposers help in decomposing dead plants and animals, they act as cleansing agents of the environment.Also, the decomposers recycle nutrients from dead plants and animals, and their waste back to the ecosystem.

Without decomposers, there would be a lot of dead plants and animals. Hence, the soil would lack nutrients plants need to grow and the entire ecosystem would break down.
