  1. Energy & Matter Chapter 11

  2. Ecosystem Function • One-way flowof energy • Cycling ofmatter

  3. Matter and Energy Flow in Ecosystems • Food chains • Food webs Trophic levels

  4. Agave Agave Prickly pear cactus Prickly pear cactus Roadrunner Roadrunner Diamondback rattlesnake Diamondback rattlesnake Darkling beetle Darkling beetle Bacteria Bacteria Kangaroo rat Kangaroo rat Red-tailed hawk Producer to primary consumer Gambel's quail Primary to secondary consumer Yucca Jack rabbit Collared lizard Secondary to higher-level consumer All producers and consumers to decomposers Fungi

  5. Ecological Pyramids • Pyramid ofenergy flow • Ecologicalefficiency (10%) • Pyramid ofbiomass • Pyramid ofnumbers

  6. Ecological Efficiency • 48 different studies - range of 2 to 24% trophic level transfer efficiencies • Average was 10.13%

  7. Energy Productivity of Ecosystems • Primary productivity • Secondary productivity Energy stored/area/time

  8. Matter Cycling in Ecosystems -Biogeochemical or nutrient cycles -Hydrologic cycle (H2O) -Atmospheric or gaseous cycles (C, N) -Sedimentary cycles (P, S)

  9. Hydrologic (Water) Cycle Driven by physical forces

  10. The Carbon Cycle Driven by biological forces: photosynthesis and respiration

  11. The Nitrogen Cycle Root nodules on legumes Cyanobacteria Driven by biological forces: bacteria

  12. The Phosphorus Cycle Driven by physical forces
