Which populations would benefit the most from the presence of decomposers?

Producers (plants) would benefit most from the presence of decomposers.

Explanation:

The act of recycling practiced by decomposing beings plays an important role in the ecological balance of the planet, because in addition to putting an end to the organic remains of dead beings, they produce nutrients. These nutrients are essential for the continuity of life within ecosystems. Plants, for example, are extremely dependent on this process as they need to absorb nutrients in the soil to grow. As the plants represent the producer population, it can be said that the producers will benefit most from the presence of decomposers.

Deltas are beautiful landforms, especially when viewed from above. Roughly triangular in shape, deltas are full of complex, wonderful detail: swirling, multi-colored sediments broken by serpentine, miniature river channels.
