  1. Ecology Succession Trophic Levels Food Webs Biomes

  2. Ecological Successions • Series of predictable changes that occur over time in response to disturbances. • Two types • Primary –Occurs on “new” ground (little/no soil) • Glacier melt • Volcanic lava/ash • Secondary • Disturbance over existing soil (ex. old farmland)

  3. Primary Succession • Occurs where no ecosystem was before. • On rocks, cliffs • Soil building occurs

  4. Primary Succession • Soil particle sizes: how they are classified:

  5. Primary Succession Volcano addingnew land to Hawaii

  6. Primary Succession Lichens begin growing

  7. Mosses on rocks

  8. Primary succession can be seen happening on the sidewalks. • If left alone, even NYC would return to a cement filled woodland.

  9. Primary Succession Grasses and other species begin to cover in subsequent years

  10. Primary Succession Grasses and other species begin to cover in subsequent years

  20. Trophic Levels Tertiary Consumers(Carnivores – eat carnivores) Top two also contain Omnivores (Eat plants and animals) Secondary Consumers (Carnivores – eat herbivores) Primary Consumers (Herbivores – eat plants) Producers (Plants) Decomposers (bacteria and fungi)

  21. Trophic Levels How the numbers of these type organisms actually compare to each other.

  22. Energy Flow

  23. Food Webs An example of a Food Web Shows how many organisms are interconnected by different paths.

  24. Food Chain Food chains are different from food webs. Chains only show ONE path of energy flow.

  28. Biomes

  29. Biomes

  30. Biomes • Tropical Rain Forest

  31. Biomes • Tropical Rain Forest • Tropical Dry Forest

  32. Biomes • Tropical Rain Forest • Tropical Dry Forest • Savannah

  33. Biomes • Tropical Rain Forest • Tropical Dry Forest • Savannah • Desert

  34. Biomes • Tropical Rain Forest • Tropical Dry Forest • Savannah • Desert • Grassland

  35. Biomes • Tropical Rain Forest • Tropical Dry Forest • Savannah • Desert • Grassland • Temperate Woodland/shrubland

  36. Biomes • Tropical Rain Forest • Tropical Dry Forest • Savannah • Desert • Grassland • Temperate Woodland/shrubland • Temperate Forest

  37. Biomes • Tropical Rain Forest • Tropical Dry Forest • Savannah • Desert • Grassland • Temperate Woodland/shrubland • Temperate Forest • NW Coniferous Forest

  38. Biomes • Tropical Rain Forest • Tropical Dry Forest • Savannah • Desert • Grassland • Temperate Woodland/shrubland • Temperate Forest • NW Coniferous Forest • Taiga
