Question

Why is digestion a necessary process for animals?

Answer 1

Digestion is necessary for animals to break down food into smaller particles that can be absorbed and used by their bodies, providing them with the energy and nutrients they need to survive.

Step-by-step explanation:

Digestion is a necessary process for animals because it allows them to break down food into smaller particles that can be absorbed and used by their bodies. Without digestion, the large molecules found in food, such as carbohydrates, proteins, and fats, would be unable to pass through the cell membranes and provide the energy and nutrients animals need to survive. Enzymes play a crucial role in digestion by speeding up the breakdown of these large molecules into smaller, usable molecules. Through the process of digestion, animals are able to obtain nutrition and energy from their food.

Answer 2

It is important because it breaks down the food eaten by the animals into nutrients which are needed for their bodies to function well. Not only it is important to animals but also to humans. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
