Verified step by step guidance

1. Step 1: Begin by understanding the definitions of the terms provided in the options: ecosystem, community, population, and biosphere. Each term represents a different level of biological organization.
2. Step 2: Define 'ecosystem': An ecosystem includes all living organisms (biotic factors) in a particular area, along with the non-living components (abiotic factors) such as air, water, and soil, interacting as a system.
3. Step 3: Define 'community': A community consists of all the populations of different species living and interacting in a specific area. It focuses only on the biotic factors (living organisms).
4. Step 4: Define 'population': A population refers to a group of individuals of the same species living in a specific area at the same time.
5. Step 5: Define 'biosphere': The biosphere encompasses all ecosystems on Earth, representing the global sum of all living organisms and their interactions with the environment. Based on these definitions, identify which term best describes all the organisms on your campus.
