saveliy_v [14]

Answer:

B. active transport

Explanation:

When a substance is to be transported from the area of its lower concentration to the area of its higher concentration, energy is consumed.

Therefore, the given bacterium needs to use the process of active transport to absorb the nutrients from the surroundings.
