(c) The five steps of nutrition in the correct sequence are: 
1) Ingestion - It includes the processes that take place while the food is in the mouth also known as a buccal cavity and swallowing of the food - which sends it onward down the digestive tract.
2) Digestion - It is the process of breaking down food into simpler substances that can then be absorbed and assimilated into the tissues of the body.
3) Absorption - The digested food is absorbed into the bodily fluids from the alimentary canal. 
4) Assimilation -It is the process by which chemicals from food are taken into the cells of the body after digestion and absorption. 
5) Egestion - It is the process of removing the undigested food material from the body through the anus.
