Sentences with phrase «ecosystem structure»
"Ecosystem structure" refers to the organization and arrangement of living organisms (plants, animals, microorganisms) and their physical environment in a particular ecosystem. It includes the relationships, interactions, and patterns that exist among these elements, such as food chains, habitats, and population sizes. Full definition
