What is the organic process by which food is converted into substances that can be absorbed into the body?

Diabetes
Diaphragm
Diffusion
Digestion

The correct answer is: Digestion

Digestion is the process by which large, complex molecules in food are broken down into smaller, simpler molecules that can be absorbed and used by the body. Diabetes is a medical condition caused by the body's inability to properly use and store sugar from food. The diaphragm is a muscle involved in breathing and has no role in digestion. Diffusion is a process by which substances move from an area of high concentration to an area of low concentration, and while it is involved in some aspects of digestion, it is not the main organic process by which food is converted into absorbable substances. Therefore, the best answer is D Digestion.
