Nutrient cycle

Nutrient cycle

1) It is the systematic circulation of plant nutrients between soil, water, animals and plants. For example, green plants take water and nutrients from the soil with their roots, convert them into organic matter by photosynthesis in their leaves, which are eaten by microorganisms and animals as fruits, seeds and leaves, and pass back to the soil with their waste. Thus, the circulation of nutrients is completed.

2) Processes by which elements are extracted (extracted) from their own minerals, aquatic or atmospheric sources, or recovered from their organic form, converted into the ionic form in which biotic uptake occurs, and eventually returned to the atmosphere, water or soil.
