Expert Answer:

Holozoic nutrition is the process of obtaining nourishment by the ingestion of complex organic material, which is then digestde and absorbed.

In this nutrition, parts of plants or animals or an organism as a whole is ingested and then digested. Here, animals take the energy containing organic materials, called food, into the gut. After digestion, this food can be absorbed into the body. When this food is decomposed in oxidation reactions, it can release energy to supply for daily uses.

 

Difference:

Non-green plants show saprophytic nutrition whereas most animals show holozoic nutrition.

Holozoic organisms do not feed on decaying matter whereas saprophytes feed on decaying matter.

Holozoic organisms cannot digest their food outside the body which is possible in case of saprophytes.

Examples of organisms showing saprophytic nutrition are mushrooms and bread moulds. Examples of organisms showing holozoic nutrition are human beings, insects and monkeys .
