Definition in own words What are the levels of organization in an ecosystem from least complex to most complex? Explain definition of each. Level Definition in own words Least Complex Organism 1 single individual organism Population 2 more organism of the same species that can reproduce Community 2 or more populations of species that are biotic in a given area, NO Abiotic Most Complex Ecosystem An area where biotic and abiotic factors interact / a community and the abiotic factors interacting in a given area
