Cells get energy to perform their necessary functions by taking in nutrients from food.

Food has nutrients such as proteins, carbohydrates, fats, vitamins, water and minerals and through the process of digestion, they are processed and transformed into smaller substances that pass into the blood.The blood, as it travels throughout the body, carries nutrients to all tissues and all cells, the cells receive these nutrients and begins a series of reactions known as cellular metabolism.Within cellular metabolism, molecules are broken down and new molecules are built that are necessary for the life of cells, because they obtain energy that keeps them alive.Energy is being transformed within cells and changing shape, at the same time that the molecules carry out the chemical reactions that keep us vital and functional.

Therefore, we can conclude that cells get energy to perform their necessary functions by taking in nutrients from food.

The answer to your question is C. Cells get energy by taking in nutrients from food.

Explanation:

A. Moving water from one organelle to another is not a process to get energy but to waste energy. Cells get energy from a different process.

B. Dissolve waste products are not a process to get energy most of the cells excrete wastes.

C. By taking nutrients from food, cells get enough energy from their metabolism because nutrients are rich in chemical bonds that when they break provide energy.

D. Taking oxygen from the atmosphere is a step in the cellular respiration that helps the cell to get energy, but cellular respiration is more complex than just taking oxygen.
