Answer 1

Answer:

The correct answer would be B. Ingestion, digestion, absorption, elimination.

Digestion refers to the breakdown of complex compounds into simpler elements.

The process of the digestive system can be sequenced as:

1. Ingestion: Intake of food from outside the body. For example, in humans, food is taken in from a mouth.
2. Digestion: The breakdown of complex compounds into simpler elements. For example, polysaccharides, polypeptides, and fats are converted into monosaccharides, amino acids, and fatty acid chains and glycerol respectively.
3. Absorption: The digested food is absorbed and transported to all parts of the body. In humans, the small intestine is the major site of food absorption.
4. Assimilation: The nutrients are transported or distributed to all cells of the body where they are utilized for power generation.
5. Excretion: The undigested food is then excreted out of the body. In humans, the solid waste is excreted through the anus.
