Question

What is the difference between holozoic nutrition and heterotrophic nutrition

Answer 1

Holozoic nutrition is a type or mode of heterotrophic nutrition. In this an organism ingests or takes in whole food which is then digested in the complex digestive system of the body. For example : Human beings
Heterotrophic nutrition is the mode of nutrition in which organisms take in organic compounds prepared by other organisms like plants to meet their nutritional needs. The complex organic compounds are broken dowm into simpler forms for absorption. Example: Animals.

Holozoic vs Holophytic Nutrition
Holozoic nutrition is a heterotrophic type of nutrition in which organisms consume solid food and is composed of different steps; ingestion, digestion, absorption, assimilation and ejection.	Holophytic nutrition is a nutrition mode of plants which is also referred to as autotrophs and use solar energy and inorganic carbon as the source of energy and the source of carbon respectively.
Carbon Source
Holozoic nutrition is a mode of nutrition which uses organic C sources.	Holophytic nutrition is a mode of nutrition which uses inorganic C sources.
Types of Processes
Five main processes in holozoic nutrition such as ingestion, digestion, absorption, assimilation, egestion.	No subprocesses in holophytic nutrition.
Specific Organisms
Holozoic nutrition is shown by man and other higher forms of animals.	Holophytic nutrition is mainly found in Plants.
Digestive System
Animals which show holozoic nutrition have a well developed digestive system.	Plants which show holophytic nutrition lack digestive system
