Question

Quizplus · Accepted Answer

Nutrients are constantly cycled between the living organisms and the nonliving environment. Producers absorb nutrients from the soil or water, consumers consume producers and in turn, they are consumed by higher-order consumers, and then the decomposers break down the dead organic matter and release the nutrients back into the soil or water. This cycle ensures that nutrients are not lost and remain available for the ecosystem.
