Most organisms use food as the outside raw material for its life process

  • There are some essential food materials that are needed by our body for survival and some non essential food materials that can be synthesized by our body with the help of essential food materials. 

  • Organisms need some minerals and some vitamins that can be taken through diet which are needed for the physiological processes of our body.

  •  Also we need enzymes for the certain functions to be done in our body that can be taken from outside as raw material.
