Question

What is digestion?

Answer 1

Digestion:

1. Heterotrophs eat various types of foods and obtain their nutrition in different ways.
2. Digestion is the breakdown of macromolecules in the food we eat into small and simpler water-soluble food molecules so that they can be absorbed into the blood and used for energy synthesis.
3. Unicellular organisms have a single cell, so the food intake is by the entire cell surface.
4. Multicellular organisms have a complex body and they have specialized parts to digest food.
