Soil — BIOLOGY STD 6 — Question

Bacteria and fungi present in the soil play a major role in recycling of nutrients in the soil. Plants absorb nutrients from the soil to grow. Some plants are eaten by animals. The dead remains of these plants and animals have nutrients which are broken down by the decomposing bacteria and fungi present in the soil. Thus, the nutrients are released back into the soil. These nutrients are again used by plants and recycled.
