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

Verified step by step guidance

Understand the definitions of the terms provided in the options: ecosystem, community, population, and biosphere.

An ecosystem includes all living organisms (biotic factors) and non-living components (abiotic factors) in a specific area. Since the problem only mentions organisms, this option can be ruled out.

A community refers to all the populations of different species living and interacting in a specific area. This matches the description of 'all the organisms on your campus.'

A population refers to individuals of the same species living in a specific area. Since the problem mentions all organisms, not just one species, this option can be ruled out.

The biosphere refers to all ecosystems on Earth, encompassing all living organisms globally. Since the problem is limited to your campus, this option is not relevant.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ecosystem

An ecosystem encompasses all living organisms in a particular area, along with their physical environment, interacting as a system. It includes both biotic factors, such as plants and animals, and abiotic factors, like soil and climate. Ecosystems can vary in size and complexity, from a small pond to a vast forest.

Community

A community refers specifically to the various populations of different species that live and interact in a particular area. It focuses on the relationships and interactions among these species, such as competition, predation, and symbiosis. In the context of the question, a community would include all the organisms on campus, but not the physical environment.

Population

A population is defined as a group of individuals of the same species that live in a specific area and can interbreed. It emphasizes the dynamics of a single species, including its size, density, and distribution. In the context of the question, a population would refer to a specific species of organism on campus, rather than all organisms collectively.
