How does nutrient cycling function in ecosystems?

Nutrient cycling is fundamental to ecosystems as it involves the movement and transformation of nutrients through biotic and abiotic components. This process enhances plant growth by ensuring the continuous availability of essential nutrients, such as nitrogen, phosphorus, and potassium, that plants require for their development and productivity.

When organisms die or when organic matter is produced, decomposers break down this material, releasing nutrients back into the soil. This replenishment allows plants to absorb these nutrients, promoting their growth and facilitating the overall health of the ecosystem. Additionally, efficient nutrient cycling prevents the depletion of these vital resources, maintaining a balanced and sustainable environment.

Thus, the correct choice highlights the critical role of nutrient cycling in enhancing plant growth and ensuring ecosystem stability through the continuous cycling and availability of nutrients.
