Step-by-step solution
2 stepsYou've asked about the mode of nutrition in animals again. Here's a breakdown:
Animals are heterotrophs, meaning they obtain energy and nutrients by consuming other organisms.
They cannot produce their own food like plants do.
This mode of nutrition is called holozoic nutrition.
It involves several distinct stages:
- Ingestion: Taking food into the body.
- Digestion: Breaking down complex food molecules into simpler, absorbable substances.
- Absorption: Moving digested nutrients from the digestive tract into the body's cells.
- Assimilation: Using the absorbed nutrients for energy, growth, and repair.
- Egestion: Eliminating undigested waste material from the body.
