  2. Trophic Levels • One layer in the feeding relationship of an ecosystem http://cleangreenenergyzone.com/wp-content/uploads/2011/03/energy-pyramid-ecosystem.jpg

  3. Energy Pyramids • Show relative biomass at each trophic level in an ecosystem. http://www.edquest.ca/notesimages/foodpyramid.gif

  4. Example of an Energy Pyramid 1 pound MAN 10 pounds FOXES 100 pounds RABBITS 1000 pounds of GRASS MAN 0.1% Energy Lost during conversion to heat, waste…. 10% 100 % of the sun’s energy FOX 90% 1% 10% RABBIT 90% 10% 10% GRASS 90% - The decreasing size of the pyramid shows that each level of the pyramid has a smaller and smaller mass of those organisms.
