Which system of the body breaks down food into forms that the body can use?
excretory system
digestive system
reproductive system
respiratory system

The correct answer would be the digestive system.

The main function of the digestive system is to break down the complex food substances into simpler absorb-able form.

It is achieved by mechanical and biochemical degradation of the food.

The whole process of the digestive system can be classified into five steps ingestion, digestion, absorption, assimilation, and egestion.

Usually, polysaccharides are converted into monosaccharides (such as glucose), proteins are converted into amino acids, and fats are converted to fatty acids and glycerol.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
