Levels of Biological Organization and Ecosystem Dynamics

The video explores the levels of biological organization, starting from organisms, which are made up of cells, tissues, organs, and organ systems. It explains how organisms form populations, which together create communities. These communities, along with non-living factors, form ecosystems. The video further describes biomes as large ecosystems shaped by climate and physical environment. Finally, it discusses the biosphere, the global sum of all ecosystems, where life exists on Earth.
