Food for thought, the nutrient cycle is constantly exchanging inorganic and organic matter back and forth in an environment.
Because Earth is a closed system, nothing is taken out or in. It’s just recycled back and forth. First, plants uptake nutrients from the soil to grow.
Then, animals consume plants and make waste. Eventually, plants die and decay becoming litter in the soil. Decomposers break it down where it can be recycled to be part of the food chain again.
This vital process releases nutrients and replenishes the soil keeping the nutrient cycle in balance. This process of production and decomposition is deep-rooted and is the life blood in fully functional ecosystems.
