All the organisms on your campus make up
a. An ecosystem
b. A community
c. A population
d. A taxonomic domain

Verified step by step guidance

1. Understand the definitions of each term: An ecosystem includes all living organisms in an area along with the non-living components of the environment. A community consists of all the different species living in a particular area. A population is a group of individuals of the same species living in a specific area. A taxonomic domain is a broad classification category that includes one or more kingdoms.
2. Identify the scope of the question: The problem asks about 'all the organisms on your campus,' which implies multiple species living together in a defined area.
3. Compare the definitions with the problem: Since the problem involves multiple species, it cannot be a population, which refers to a single species.
4. Consider the non-living components: The problem does not mention non-living components, so it is not describing an ecosystem.
5. Determine the best fit: The term 'community' best describes all the organisms of different species living together in a specific area, such as a campus.

Key Concepts

Ecosystem

An ecosystem encompasses all living organisms in a particular area, along with the non-living components of their environment, interacting as a system. It includes biotic factors like plants and animals, and abiotic factors such as climate and soil, working together to sustain life.

Community

A community in biology refers to all the different species living in a particular area, interacting with each other. It focuses on the biotic components, excluding abiotic factors, and includes various populations of organisms that coexist and interact within a shared environment.

Population

A population is a group of individuals of the same species living in a specific area. It is characterized by its size, density, and genetic makeup, and is subject to factors like birth rates, death rates, and migration, which influence its dynamics over time.
