The scientific study of ecosystems is known as "ecology." Ecology examines how organisms interact with one another and their physical environment, focusing on the relationships among living organisms, populations, communities, and ecosystems. This field encompasses various sub-disciplines, including population ecology, community ecology, and ecosystem ecology. Ecologists study biodiversity, the distribution of species, and the effects of environmental changes, such as climate change and habitat destruction, on ecosystems. Understanding these interactions is crucial for conservation efforts and managing natural resources, helping ensure the sustainability and health of ecosystems and the planet.
