Solution
The answer is the first one: ingestion.
Explanation for each option:
Ingestion: This is the correct answer. Ingestion is the active process of taking food into the digestive tract via the mouth.
Excretion: This is incorrect. Excretion refers to the process of eliminating waste products from the body, not the intake of food.
Absorption: This is incorrect. Absorption is the process by which nutrients from digested food are taken into the body's cells, not the initial intake of food.
IDON'TKNOWYET: This is not a valid answer in the context of the question.
