Studying interdependence in ecosystems is significant because it reveals how species and their environments interact and rely on each other for survival. These interactions demonstrate how changes in one part of the ecosystem can affect the entire system. Understanding interdependence helps in recognizing the impact of human activities, such as pollution and habitat destruction, on ecological balance. It also provides insights into how biodiversity contributes to ecosystem resilience and stability, aiding in conservation efforts and the sustainable management of natural resources.
