Answer:
DIFFERENCE BETWEEN INGESTION AND DIGESTION
Definition
Ingestion: Ingestion refers to the process of taking food or another substance into the body by swallowing or absorbing it.
Digestion: Digestion refers to a process by which food is broken down into simple chemical compounds that can be absorbed and used as nutrients or eliminated by the body.
OCCURRENCE
Ingestion: Ingestion takes place in mouth.
Digestion: Digestion takes place in mouth, stomach, and intestine.
CORRESPONDENCE
Ingestion: Ingestion occurs first.
Digestion: Digestion follows ingestion.
IN PROTOZOA
Ingestion: Ingestion in protozoa occurs by the process.
Digestion: Digestion in protozoa occurs inside vesicles in the cytoplasm.
CONCLUSION
Ingestion is the taking in of food particles into the body. In animals, ingestion occurs in the mouth whereas in protozoans it occurs by process. Digestion is the mechanical and chemical breakdown of food into small substances, facilitating the absorption and assimilation of nutrients by the body. This is the main difference between ingestion and digestion.
