Question is what is about respiration ??
--------------------------------------------------------

Firstly tell you about life process .

Life process is most important in living organization. Without it no one we left in this world . we taking

we are human . we eat , doing so many works .
Living thing or non-living things . These two are most important .

Living thing – Living things means those things
----------------
which have life , we are living thing . we take breath from air , animals moves one place to another , we find a food for living .

Non-living things – it's mean which have no life exm. stone , chair .
in other word those things which didn't do anything without any external help .

We need energy to live . This energy will come through the food whatever we take when we are hungry .

1. Nutrition = The process of intake and utilisation of the food by an organism is called nutrition .

2 . RESPIRATION = The process of releasing energy from food is called respiration.
