Exploring The Hierarchy Of Life And Its Systems

Mr. Anderson explains the hierarchy of life, from atoms to the biosphere, highlighting how each level is a system with emergent properties. He uses termites as an example to illustrate these concepts. The video covers the organization of life from molecules to cells, tissues, organs, organ systems, populations, communities, ecosystems, and finally the biosphere.
