Answer:

Active transport

Explanation:

Active transport is defined as the movement of ions or molecules from a region of lower concentration into a region of higher concentration by the use of energy. Two examples of active transport include the uptake of glucose in human intestine and the absorption of mineral ions into plant roots.

Active transport requires energy because it involves the movement of molecules against an existing concentration gradient.
