An ecosystem refers to a complex network of interdependent organisms and physical elements that exist within a particular geographical area. It comprises both biotic and abiotic factors, where the biotic factors include all living organisms from plants, animals, and microorganisms that coexist with each other, while the abiotic factors relate to non-living elements like rocks, water, and air that are critical to the survival of these organisms. An ecosystem can take various forms, such as a forest, a marine environment, or even a human-made environment like a city park. Understanding the interdependence of different living organisms and nonliving elements in an ecosystem is vital for managing and conserving ecosystems for their long-term health and sustainability.
