Transcript

  • 1. Ecology Chapter 34
  • 2. Do Now 4/26/12 • List all the things you observe in the ecosystem below
  • 3. Now… • In your notebooks, divide your list into two categories: 1. Living things 2. Non-living things 3. Both? What was living? What is non-living? Both?
  • 4. Do Now • Take out your list of “living, non living and both” things.
  • 5. Biotic and Abiotic Factors • We are going to watch a video about Biotic and Abiotic Factors in an environment. As you watch write 1-2 sentences about what they are and how they are related. Let’s watch!
  • 6. Biotic Factors • Bio = _________ • Biotic Factors = anything in an environment that influences/interacts with an organism that is LIVING
  • 7. Abiotic Factors • “A” = ____ “bio” = _________ • Abiotic Factors = anything in an environment that influences/interacts w/ an organism that’s NON-LIVING
  • 8. Both? • Mixtures of the two • Examples • Mud (abiotic) may contain bacteria (biotic) mixed in • Pond water (abiotic) has microorganisms (biotic) that we can’t see
  • 9. Do Now 5/3/12 • What factors (things) influence or interact with an organism in its environment?
  • 10. Ecology • Eco = _________ -ology = _________ • Ecology = the study of organisms, their environment and how they are interrelated (inter = ________)
  • 11. Levels of Organization • Smallest  Largest • Species (Individual) • Population • Community • Ecosystem • Biome • Biosphere
  • 12. Do Now 5/10/11 • Describe how the abiotic and biotic factors are related in this picture. Give at least 3 specific examples 
  • 13. Species • Similar organisms that can reproduce with each other
  • 14. Population • Group of individuals of the same species, they live in the same area
  • 15. Community • Different populations (species) living in a similar area
  • 16. Ecosystem • A community, the environment and their interactions
  • 17. Biome • Ecosystems (communities + environment) with similar climates and organisms
  • 18. Biosphere • Bio = ______ Sphere = _______ • Earth! • The entire planet…all living (biotic) and non-living (abiotic) environments
  • 19. Activity • Draw a circle and label it “Me”. Then draw five concentric circles and label each of them with the appropriate level of organization. Describe your population, community, etc.
  • 20. Activity • Each of you will be assigned a different Biome: • Tundra, Deciduous forest, Coniferous Forest, Grassland, Shrubland, Rainforest, Desert • For each Biome, make an Informational Poster that includes the following: • A description of the Biome, or any facts about it • Abiotic Factors: describe the weather, climate, and other non-living environments/factors • Biotic Factors: describe the animal life, plant life and examples
  • 21. Energy in Ecosystems • Primary Producers: aka Autotrophs • Use solar (sun) or chemical energy to make “food” • Photosynthesis: use sunlight to make energy • Algae and plants • Chemosynthesis: use chemicals from earth to make energy (without sunlight) • Some bacteria, in hydrothermal vents • Full of energy  used by other organism
  • 22. Energy in Ecosystems • Consumers: aka Heterotrophs • Get energy and nutrients from other organisms • Different types: 1. Carnivores 2. Scavengers 3. Decomposers 4. Detritivores 5. Herbivores 6. Omnivores
  • 23. Activity • Choose a type of consumer • Describe what that type of consumer eats • Give at least 3 examples of that consumer • Draw a picture of an example of that consumer • Extra Credit! Come up with a fun way to remember what that consumer eats
