  1. Ecology By: Anthony Michielini

  2. What is ecology?

  3. study of how organisms interact with each other and how they interact with their environment

  4. What is Individual organisms?

  5. Smallest unit of study that ecologists concern themselves with.

  6. What are Species?

  7. same type of organism that lives in the same place at the same time. • capable of reproducing and producing fertile young

  8. What are Populations?

  9. groups of the same species that may or may not interact with each other. • Many different ways to divide up population

  10. What is Communities?

  11. Groups of populations that are interacting with each other at any given day or any given time

  12. What is an Ecosystems

  13. Lots of habitats in a generalized area put many ecosystems together and you get a biome.

  14. What’s a Biosphere?

  15. All of the places on earth that living things survive, anywhere there is life would contribute to the biosphere

  16. What’s a Habitat?

  17. Groups of communities all with very similar biotic and abiotic conditions

  18. What’s Abiotic Factors?

  19. Non living things

  20. What’s Biotic Factors?

  21. Living things

  22. What are producers(first Tropic level)?

  23. Autotrophs - Producers, plants • Gets energy from the sun – most energy is found here • Biggest level

  24. What are Primary Consumers(Second Tropic Level)?

  25. First level consumer – herbivore • 90% of energy is lost as you move up the pyramid

  26. What are Secondary Consumers(Third Tropic Level)? • Carnivores or omnivores • 10% of energy is left over on this level

  27. Tertiary Consumer (Fourth Tropic Level)?

  28. Carnivores of omnivores • 1% of energy is left over on this level for those organisms to use

  29. What are Quandary Consumer(Fifth Tropic Level)?

  30. Very little energy at this level • Usually rare to be at this level

  31. What is the difference from a food pyramid and a food web?

  32. Food pyramid – like a chain with a specific order • Food web – more complicated with different paths being followed

  33. What is a Decomposer?

  34. Similar to saprobes • recycle nutrients back into the soil as they consume the dead • EX: bacteria, mushrooms, and insects

  35. What is an Autotroph?

  36. An organism that makes its own food. • EX: plants and algae

  37. What is a Heterotroph?

  38. organism that obtains its nutrients from other organisms. • EX: humans, lions, and mushrooms

  39. What is a herbivore?

  40. Something that only eats plants. • EX: giraffe and elephant

  41. What is a Carnivore?

  42. Organism that only eats meat • EX: lions, tigers, and bears

  43. What’s an omnivore?

  44. Something that eats both meat and plants • EX: humans

  45. What is a saprobe?

  46. A decomposer • Gets rid of remaining material when things die

  47. What is a scavenger?

  48. Something that eats other dead organisms • EX: crow and hyena

  49. What is Amensalism?

  50. organism benefits and kills the other organism • EX: Black walnut tree, penicillin
