Which of the following best explains the concept of ecological interdependence?

The concept of ecological interdependence is fundamentally about the relationships between different species and their environments, emphasizing how species depend on one another for survival. This interconnectedness means that the actions or changes in one species can have significant impacts on others within the same ecosystem. For instance, predators rely on their prey for food, while plants provide oxygen and habitat for animals. This mutual reliance illustrates the balance necessary for ecosystems to function sustainably.

In contrast, other options like the isolation of ecosystems, competition among species for resources, and the independence of ecosystems do not accurately represent the holistic and interrelated nature of ecological systems. Ecosystems are typically characterized by interaction rather than isolation, and while competition is a factor, it does not capture the entirety of interdependence, which also includes cooperation and mutual benefits. Therefore, the reliance of species on each other for survival accurately encapsulates the essence of ecological interdependence.
