Ecology Concepts and Interactions

The video explores the organization of life, starting from cells, the basic unit of life, to tissues, organs, organ systems, and complete organisms. It then expands to populations, communities, ecosystems, biomes, and finally the biosphere. The video discusses how living and nonliving factors interact at each level, influencing life on Earth.
