10 Food Chain Linear They show the flow of energy Length limited by available energy

11 Food Web Expanded More complex Producers Major plants Primary consumers Animals that eat plants Secondary consumers Animals that eat herbivores Higher consumers More complicated because they may be both secondary and tertiary Decomposers Fungi, bacteria that eat the dead

12 ECOLOGICAL PYRAMIDS Pyramid of energy Least Energy = top consumers Most Energy = producers 10% of energy available at each trophic level is converted into new biomass at above level Pyramid of numbers Least = top consumers Most = producers Pyramid of Biomass energy transferred energy lost tertiary consumers secondary consumers primary consumers producers 75 g/m2 150g/m2 675g/m2 2000g/m2 producers 2000g/m2 tertiary consumers secondary consumers primary consumers producers ,000 5,000,000 producers
