Answer 1

Answer: (B)

Release stored nutrients by breaking down complex organic molecules into the simple molecules required for primary productivity

Microorganisms are the decomposers as they break-down the complex organic substances into simple inorganic substances that go into the soil and are used up once more by the plants.

So, option B is correct.
