The term for the interaction of organisms with their physical environment is called ecological interaction. This encompasses the relationships and exchanges between organisms, such as predation, competition, symbiosis, and nutrient cycling, within their habitats. These interactions are crucial in shaping ecosystems, influencing population dynamics, and determining how organisms adapt and thrive. Additionally, studying ecological interactions helps researchers understand the impacts of environmental changes and human activities on both ecosystems and individual species, guiding conservation efforts and ecosystem management strategies.
