Question

Do insects have a digestive system?

Answer 1

Explanation:

1. The digestive system of insects is closed.
2. All insects have a fully functional digestive system. Insects have a lengthy, muscular, and tubular alimentary canal that runs from their mouth to their anus.
3. It is divided into three sections: the foregut, the midgut, and the hindgut. Insects use their digestive systems to draw nutrients and other ingredients from the food they eat.
4. The majority of this food must first be broken down by catabolic reactions into smaller particles (i.e., amino acids, simple sugars, etc.) before it can be used by the body's cells for energy, growth, or reproduction.
5. These complex compounds include proteins, polysaccharides, fats, nucleic acids, and others. Digestion is the term for this process.

Hence, the digestive system is present in insects.
