Ecologists study living systems across different hierarchical scales. Match each ecological level of organization with its correct definition.
- PopulationA group of individuals of the same species living in a specific area
- CommunityAll interacting populations of different species coexisting in a shared area
- EcosystemA biological community of organisms interacting with their non-living physical environment
- BiosphereThe entire zone of life on Earth, encompassing all ecosystems and biomes
Answer
Population pairs with 'A group of individuals of the same species living in a specific area'; Community pairs with 'All interacting populations of different species coexisting in a shared area'; Ecosystem pairs with 'A biological community of organisms interacting with their non-living physical environment'; Biosphere pairs with 'The entire zone of life on Earth, encompassing all ecosystems and biomes'.
Each ecological level builds hierarchically: single-species groups form populations, multiple populations form communities, communities combined with abiotic factors form ecosystems, and all ecosystems together constitute the planetary biosphere.
