Answer:
Nutrition
Step-by-step explanation:
Here, the answer cannot be absorption or digestion just because they are asking about intake of food, water and minerals. Digestion is a full fledged process during which food is chemically and mechanically transformed into a form through which energy can be obtained. The oprocess of digestion requires a complete digestive system that can be as simple as a vacuole in unicellular organism like eubacterium or as specialized as those of mammals like humans. Its not just about intake of food, but process of food transformation.
On the other hand, nutrition at cellular level is the process in which nutrients are obtained in any form, whether minerals, food or water. These nutrients act as our dietry supplementation and constitute the basics of our healthy diet.
Therefore, Nutrition is the correct answer.
Hope it helps! :)
