Ecosystems maintain nutrient cycling through a series of interconnected processes that allow nutrients to be recycled and reused within the ecosystem. This includes processes such as decomposition, where dead organisms are broken down by decomposers like bacteria and fungi, releasing nutrients back into the soil. Nutrients are also absorbed by plants through their roots and then passed on to herbivores through consumption. When these herbivores are eaten by predators, the nutrients are passed up the food chain. In addition, some nutrients can also be cycled through the atmosphere, soil, and water within the ecosystem. Overall, these processes work together to ensure a continuous flow of nutrients within the ecosystem, supporting the growth and survival of organisms within it.
