Which of the following represents the four levels of ecological organization?

The four levels of ecological organization are population, community, ecosystem, and biosphere.

Starting with the population level, this encompasses groups of individuals of the same species living in a specific area, highlighting their interactions and patterns such as birth rates and death rates. Following that is the community level, where multiple populations of different species interact within a particular environment, forming relationships that can shape the dynamics of the ecosystem.

Next is the ecosystem level, which includes the community along with the abiotic (non-living) components of the environment, including soil, water, and climate. This level emphasizes how energy flows and nutrients cycle through both living and non-living elements. Lastly, the biosphere represents the highest level of organization, encompassing all ecosystems on Earth, integrating the complex relationships and interactions that support life across various regions.

This framework provides a structured understanding of ecological interactions, from individual organisms to the global scale, illustrating how interconnected and interdependent all life forms are.
