Question

What are the differences between digestion and absorption?( 4 points ).

Answer 1

Answer:

Ingestion and digestion are two actions that occur in the alimentary canal of animals. The main difference between ingestion and digestion is that ingestion is the taking of food into the body whereas digestion is the breakdown of food into small molecules that can be absorbed by the body. Ingestion can be taking food either into the mouth in animals or into the cytoplasm in protozoans. Mechanical digestion and chemical digestion are the two types of digestions. In mechanical digestion, large food particles are broken down into small food particles. This increases the surface area of food, facilitating their chemical digestion by enzymes. Chemical digestion facilitates the absorption of nutrients from the alimentary canal.

Answer 2

Answer:

Explanation:

Digestion is the process in which the food is broken down into smaller, simpler pieces. For example breaking down Carbohydrates into simple sugar, or fats into fatty acids and glycerol.

Absorption takes place after the food has been broken down. The food gets out of the alimentary canal and into the bloodstream, so that it can be used by the animal.
