  1. The universe is dynamic. When we are creative, we are the most alive and in touch with it. --Brad Dourif

  2. Biodiversity

  3. O What A Tangled Web… www.youtube-nocookie.com/embed/xHkq1edcbk4?rel=0 Video: Wings of Life

  4. Flow of Energy in Ecosystems Solar radiant energy captured = about 1%

  5. 17% growth

  6. 17% growth 33% cellular respiration

  7. Amount of chemical-bond energy decreases as energy is passed from one trophic level to the next • 50% of chemical-bond energy is not assimilated and is egested in feces • 33% of ingested energy is used for cellular respiration • 17% ingested energy is converted into insect biomass • Some is available to next consumer 17% growth 33% cellular respiration 50% feces

  8. Trophic levels: what you eat! Producers/Autotrophs Consumers/ Heterotrophs

  9. Ecosystems - Communities and their physical environments, which interact and are interconnected by physical, chemical and biological processes

  10. Energy Flow • Producers - Photosynthesize and store produced energy • Plants, algae • Primary consumers - Feed on producers • Cows, caribou, caterpillars • Secondary consumers - Feed on primary consumers • Tigers, toads • Decomposers - Break down organic material to forms that can be reassimilated by producers • Bacteria, fungi

  11. Ecosystems: • Producers and consumers interact, forming food chains or food webs. • Determine flow of energy through different levels

  12. Ecosystems: • Trophic efficiency - Percentage of available energy actually transferred from one trophic level to next

  13. Pollinators USFWS • Birds • Bats • Insects • Bees • Butterflies & Moths • Flies • Beetles • Wasps USFWS Dean E. Biggins, USFWS

  14. Unusual Pollinators Mammals: Opossum Rats Flying Fox Lemur Lizards!

  15. The Workhorse Pollinator Honeybees: Apis Threats: Colony Collapse Disorder Disease Invasive Species

  16. Importance of Pollinators • More than 80% of flowering plants depend on animal pollinators • In U.S., over 100 crop plants depend on animal pollinators (value >$15 Billion) • Most natural ecosystems would collapse without animal pollinators • Some plants are endangered because of diminished pollination • Chocolate depends on pollinators!!
