  1. ECOLOGY ECOLOGY Levels of Organization pg. 63 Levels of Organization pg. 63

  2. Ecology: What is it? • Ecology – the study of the interactions of living organisms with one another and their environment

  3. Levels of Organization 1. ORGANISM • One individual from a population • Example: alligator

  4. Levels of Organization 2. POPULATION • Group of individuals of the same species that live together • Example: alligators living in the same area

  5. Levels of Organization 3. COMMUNITY • All the populations of species that live in the same habitat and interact with each other • Example: Population of alligators and all the species they interact with.

  6. Levels of Organization 4. ECOSYSTEM • Community of organisms and their abiotic environment • Example: the swamp where the alligators live

  7. Levels of Organization 5. BIOSPHERE • Parts of the Earth where life exists • Ex. deepest oceans, highest sky

  8. POPULATION ORGANISM ECOSYSTEM COMMUNITY BIOSPHERE

  9. Create your own example of the LEVELS OF ORGANIZATIONDrawn and colored neatly, due Thursday! Levels of Organization BRAINSTORM And PLAN! Organism Population Community Ecosystem Biosphere

  10. Abiotic vs. Biotic Factors Page 64

  11. Abiotic vs. Biotic Factors • Ecologist divide environment factors that influence organisms into two groups: • ABIOTIC • BIOTIC

  12. BIOTIC ABIOTIC

  13. BIOTIC FACTORS • Living or once living parts of the environment • Arranged into the levels of organization

  14. ABIOTIC FACTORS • Nonliving parts of the environment

  15. BIOTIC ABIOTIC Examples: (10) - - - - - - - - - Examples: (10) - - - - - - - - -

  16. BIOTIC (living) ABIOTIC (nonliving) Examples: 3. Grass 4. Tree 5. Mouse 7. Deer 8. fungus 11. Bacteria 14. Cactus 18. Dead frog 19. Decomposing tree 20. Flower • Examples: • Sunlight • Temperature • 6. Rock • 9. Water • 10. Soil • 12. Hair • 13. Plastic • 15. Sand • 16. Air • 17. wind

  17. Bellwork – Monday 2/27 • Pick up the bellwork review sheet from the front table. • Use your comp. book to complete. • Turn face down when finished.

  18. page 66

  19. Consumers Producers Decomposers

  20. Living things need energy! • How do we get energy? • How do plants get energy? • Organisms in a community can be divided into three groups: - Producers - Consumers - Decomposers

  21. PRODUCERS • Producers – organisms that use sunlight directly to make food (photosynthesis) • Examples – plants, algae, GREEN • What does produce mean?

  22. CONSUMERS • Consumers – organisms that eat other organisms to get their energy. What does consume mean?

  23. Types of Consumers • Herbivore – an animal that eats only plants • Examples: grasshopper, prairie dogs, and bison • Carnivore – an animal that eats other animals • Examples: coyotes, hawks, owls • Omnivore – an animal that eats plants and animals • Examples: mice, bears, humans

  24. DECOMPOSERS • Decomposers- organisms that get energy by breaking down dead organisms • Examples – worms, fungi, and bacteria

  25. Bellwork 2/28Be ready with an answer.

  26. PICK UP BELLWORK SHEET FROM FRONT LAB TABLE.Complete and turn in before lunch!

  27. EnergyPyramid/Trophic Levels pg. 67Can you identify the producer and consumers? consumer consumer consumer producer

  28. Energy Pyramids Show: • Trophic Levels • Flow of energy in an ecosystem • Decreasing energy for higher consumers • Large amounts of producers are needed • Only 10% of energy is passed from level to level, 90% is wasted!

  29. Glue in on page 67

  30. low TERITIARY CONSUMERS small SECONDARY CONSUMERS ENERGY POPULATION PRIMARY CONSUMERS high PRIMARY PRODUCERS large

  31. Create Your Own Trophic Pyramid • Partner Activity • When finished: • Title your poster. • Show 10% energy transfers per level. • Color your pictures. WRITE THE WHOLE STATEMENT WITH THE ANSWER AROUND YOUR PYRAMID, not just the answers!

  32. Bellwork 3/2page 68 – Food Chain vs. Food Web

  33. Food Chain • Food chain – a diagram that shows one path of energy flowing from one organism to another

  34. Food Web • Food web- shows multiple paths of the feeding relationship between organisms in an ecosystem

  35. You have 10 minutes at the beginning of class to work on the tasks from yesterday!Everyone start with Task 2. If you have that done, work on any others that are incomplete.

  36. Types of Interactions – pg. 69

  37. With your group use prior knowledge… • Discuss the meaning of the following terms: • MUTUAL • PARASITE • ADAPT • COMMENSAL

  38. SYMBIOISIS • Relationship with two different organisms living in close association with each other • There are three kinds: - mutualism - commensalism - parasitism

  39. MUTUALISM • Relationship where both species benefit
