Biological Levels in Biology: The World Tour

The video introduces the biological levels of organization, starting from the cellular level, which is the basic unit of life. It explains how cells form tissues, which then form organs and organ systems. These systems make up an organism. The video further explores how organisms form populations, which combine to create communities. When abiotic factors are included, these communities form ecosystems. Multiple ecosystems across the globe form biomes, and all biomes together constitute the biosphere. The video emphasizes the importance of understanding these levels to relate them to each other and the whole system.
