QUESTION:

Food is considered as the major source of energy for all organisms. why is there a need to break down this food?

ANSWER:

• Organisms use the stored energy in food to fuel all living processes. Food is organic molecules that serve as fuel and building material for all organisms. The breakdown of food molecules enables cells to store energy and to carry out the many functions of the cell and therefore the entire organism.

• The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.
