The term used to describe the relationship between organisms and their environments is ecological interaction. These interactions encompass various types, including predation, competition, and symbiosis, all of which significantly impact ecosystem dynamics. For example, predators regulate prey populations, while competition among species for resources can lead to niche differentiation and evolutionary adaptations. Additionally, mutualistic relationships enhance nutrient exchange and ecosystem stability. Understanding these interactions helps elucidate the complexity of ecosystems and is essential for effective management and conservation efforts aimed at maintaining biodiversity and ecological health.
