Question

define absorptive and holozoic nutrition

Answer 1

Absorption: The active and passive transport of the chemical products of digestion out of the food-containing compartment and into the body or cytoplasm.Assimilation: Utilization of the absorbed molecules for various metabolic processes. Egestion: The expulsion of undigested material, commonly called defecating.
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:
