  1. Ecology Biomes and Ecosystems

  2. Ecosystems- Matter and Energy

  3. Primary Production http://www.bigelow.org/foodweb/chemosynthesis.jpg

  4. Visualizing Matter & Energy There are a variety of diagrams that help us visualize how energy, biomass, matter, and even number of organisms interact in a particular community or ecosystem. It is important that you look carefully at the diagrams and understand what it says about that ecosystem in terms of matter and/or energy.

  5. Primary Production made by Primary Producers Gross primary productivity is the total amount of energy that producers convert to chemical energy in organic molecules per unit of time. Then the plant must use some energy to supports its own processes with cellular respiration such as growth, opening and closing it’s stomata, etc. What is left over in that same amount of time is net primary productivity which is the energy available to be used by another organism.

  6. Primary Production

  7. Net Product Pyramid

  8. Trophic Level Human Population

  9. Biomass Pyramids • I think this slide should go up with the other pyramid slides even though it’s about populations

  10. Pyramid of Numbers

  11. Energy Transformation

  12. Biogeochemical Cycle

  13. Nitrogen Cycle

  14. Phosphorus Cycle

  15. Water Cycle

  16. Carbon Cycle

  17. Nutrient Cycling

  19. Now that we have examined the flow of energy and the cycling of matter, let’s examine biomes from the biosphere.

  20. Aquatic Biome Distribution

  21. Lake Stratification

  22. Zonation Marine Zonation Lake Zonation

  23. Freshwater

  24. Wetlands & Estuaries Transitional Zones between freshwater and marine. This water tends to be a mix of both depending on its geographic location. The water is often referred to as brackish

  25. Marine Biomes Tide Zone Coral Reef Benthos Black Smoker

  26. Terrestrial Biomes

  27. Tropical Rain Forest

  28. Savanna

  29. Desert

  30. Chaparral- also called Scrubland

  31. Temperate Grasslands

  32. Temperate Forest

  33. Taiga Also called Coniferous or Boreal Forest 1. precipitation usually snow 2. conifers like spruce, fir, hemlock 3. soil acidic and forms slowly

  34. Tundra

  35. Biosphere

  36. What happens when a cycle is out of balance? Cycles can have an anthropogenic (man-made) or a non-anthropogenic (natural phenomena) impact that causes a cycle to become unbalanced. Additionally, this may just be the natural state of that ecosystem as a consequence of the availability of nutrients. Two examples involving imbalanced freshwater habitats include: Oligotrophic waters- low primary productivity Eutrophic waters- high primary productivity

  37. Eutrophic Oligotrophic Lake

  38. Eutrophication- The Algal Bloom

  39. Experimental Data The following data was collected from 14 different rivers in Virginia. Use the Station 1 data to calculate the Primary Productivity of a water sample. Report your answer in units of mg Carbon fixed/Liter The needed conversion factors are found on the student formula sheet

  40. Answers to Previous Slides Station 1 4.2 mg O2/L  0.698 = 2.9 mL O2/L 2.9 mL O2/L  0.526= 1.6 mg Carbon fixed/L
