Ecological systems refer to the complex networks of living organisms and their physical environment, interacting as a cohesive unit. These systems can range from small ponds to vast forests, each supporting diverse forms of life and contributing to the planet's overall health. Understanding these systems is crucial for conservation efforts and sustainable development. Within ecological systems, various components such as producers, consumers, and decomposers play vital roles in nutrient cycling and energy flow. The balance of these interactions determines the resilience and stability of ecosystems, highlighting the importance of preserving biodiversity to maintain ecological integrity.
