Verified step by step guidance1
Understand the levels of ecological organization: These levels include organism, population, community, ecosystem, biome, and biosphere, arranged from simplest to most complex.
Define the term 'organism': An organism is an individual living entity, such as a single animal, plant, fungus, or microbe. It is the most basic unit of life in ecology.
Compare the other options: A population consists of multiple organisms of the same species living in a specific area. A community includes multiple populations of different species interacting in a shared environment. An ecosystem encompasses both the living (biotic) and non-living (abiotic) components of a specific area.
Identify the simplest level: Since an organism is a single living entity and does not involve interactions with others or the environment, it is the most basic level of ecological organization.
Conclude that the correct answer is 'organism' because it represents the foundational unit in the hierarchy of ecological organization.
