Presentation Transcript

  1. Ecosystem Ecology AP Bio Ch. 55

  2. Community vs. Ecosystem

  3. Abiotic Shapes Biotic • Abiotic factors create different environmental conditions • Biotic life has evolved to live in these areas • Major Factors: • Temperature • Rainfall

  4. energy • Thermodynamics • No energy created, no energy destroyed: Energy Transfers • Entropy increases in our universe

  5. Energy & life

  6. Energy & Life

  7. Energy (Food Web) • Energy Flows into and out of the biosphere

  8. Trophic Relationships • Detrivores (decomposers) • eat dead organisms • Omnivores (heterotrophs) • Eat plants and animals • 3° Consumers (carnivores) • eats 2° Consumers • 2° Consumers (carnivores) • eats 1° Consumers • 1° Consumers (herbivores) • convert chemical energy into ATP • Producers (autotrophs) • convert light energy into chemical energy

  9. Quantifying Energy

  10. Energy Calculations • GPP: the amount of energy enters plant • NPP: the amount of energy available to consumers • NPP = GPP (total energy) – R (energy used for respiration)

  11. Energy Pyramid

  12. Biomass Pyramid

  13. The data in the table below relate to the transfer of energy in a small clearly defined habitat. The units in each case are in kJ.m-2.yr-1 • Construct an energy flow model to represent all these data • Calculate the Net Productivity for • Producers • Consumers • Decomposers
