Answer
Ingestion of solid food particles occurs in holozoic nutrition (also called heterotrophic nutrition). This feeding method involves:
- Ingestion: Taking in solid or liquid food
- Digestion: Breaking down complex food molecules into simpler, absorbable forms
- Absorption: Taking up digested nutrients into cells
- Assimilation: Using absorbed nutrients for energy and growth
- Egestion: Eliminating undigested waste
Holozoic nutrition is characteristic of most animals, including humans, protozoans like Amoeba and Paramecium, and carnivorous plants like Venus flytraps. This contrasts with other nutritional modes like saprophytic (feeding on dead matter), parasitic, or autotrophic (photosynthetic) nutrition.
