The Hierarchy of Life

The video tutorial explains the hierarchy of life, starting from atoms and progressing to the biosphere. It highlights the concept of emergent properties, where new characteristics appear at each level of biological organization. The tutorial uses termite colonies as an example to illustrate these properties. It covers various levels, including atoms, molecules, macromolecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, biomes, and the biosphere.
