Energy Flow in Ecosystems
008 - Energy Flow in Ecosystems
In this video Paul Andersen explains how energy flows in ecosystems. Energy enters via producers through photosynthesis or chemosynthesis. Producers and consumers release the energy from food through cellular respiration. An explanation of gross primary productivity and net primary productivity are included. Energy and biomass in ecological pyramids show energy efficiency.
