Loops in ecology

In ecology, loops refer to interconnected pathways where energy, nutrients, or matter cycle repeatedly within an ecosystem. Unlike simple linear processes, loops show how these elements are continuously exchanged among organisms, soil, water, and the atmosphere. For example, the nitrogen cycle involves bacteria converting nitrogen into forms plants can use, which then feed animals, and waste or dead organisms return nitrogen to the soil. These loops help maintain balance and stability in ecosystems, ensuring resources are recycled and available for different living things over time.
