In an ecological context, the levels of organization typically follow this hierarchy: biosphere, ecosystem, community, population, and organism. While I cannot see the pictures, I can help you order them based on common ecological principles.
If you provide me with a brief description of what each picture represents (e.g., individual organisms, groups of the same species, different species interacting, the entire ecosystem), I can help you arrange them from the highest level to the lowest level of organization.
