which level of organization encompasses all of the others?
A. Ecosystem
B. Community
C. Population
D. Division
To determine which level of organization encompasses all of the others, we need to understand the hierarchical levels of ecological organization.
The hierarchical levels of ecological organization, from smallest to largest, are as follows:
1. Individual: An individual organism of a particular species.
2. Population: A group of individuals of the same species living in the same area.
3. Community: All the populations of different species living and interacting in the same area.
4. Ecosystem: A community of organisms, along with the physical environment, in which they interact.
5. Biosphere: The highest level of organization, encompassing all ecosystems on Earth.
Based on these levels, the option that encompasses all the others is the Biosphere. The biosphere includes all the ecosystems, communities, populations, and individuals on Earth.
Therefore, the correct answer is not provided in the options given.
