The document discusses the different levels of biological organization from lowest to highest: cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and the biosphere. It provides descriptions and examples of each level. Activities are included where students identify levels of organization from images and fill in blanks with the correct biological term. The purpose is to teach students about the hierarchical organization of living things from cells to the entire biosphere.
