Energy Processes in Living Organisms

Mr. Sonberg introduces biology students to the concept of the biosphere, explaining its components: atmosphere, lithosphere, and hydrosphere. He discusses how energy enters the biosphere and is utilized by living organisms through processes like cellular respiration and photosynthesis. The video highlights the interdependence of these processes and introduces chemosynthesis as an alternative energy source in environments without sunlight.
