Answer 2

Answer:

Bacteria obtain their nourishment through the absorptive mode of nutrition.

They secrete the extracellular digestive enzymes through the Secretion system, present in the bacterial membrane.

These enzymes digest the nutrient present in the extracellular environment.

Then they absorb the digested simpler form of the nutrient(food).
