Answers
Holozoic nutrition is a method of nutrition that involves the ingestion of liquid or solid organic material, digestion, absorption and assimilation of it to utilize it. It includes taking in the complex substances and converting them into simpler forms. Example, proteins can be broken into amino acids. This method suggests phagocytosis where the cell membrane completely surrounds a food particle. Most of the free living animals including humans exhibit this type of nutrition. In this mode of nutrition, the food may be a small bacterium, a plant or an animal. this nutrition involves:
1 Ingestion: Taking in complex organic food through mouth opening
2 Digestion: Change of complex food into simple form by action of enzymes.
3 Absorption: Passing of simple, soluble nutrients through blood or lymph.
4 Assimilation: Utilization of absorbed food for various metabolic processes.
5 Egestion: Expelling out the undigested food. This type of nutrition occurs mainly in unicellular organisms such as Amoeba. It even occurs in Humans as well, as in humans, the digestion is done through Alimentary Canal, which includes all the five processes of Holozoic Nutrition.
