  2. Ecology is

  3. What is the study of how organisms relate to each other and their environment?

  4. A distinct area, with clearly defined boundaries, with distinct abiotic conditions, and a community of interacting organisms is called this

  5. What is an ecosystem?

  6. A community is a

  7. What is a collection of different organisms living in an ecosystem?

  8. A population is

  9. What is a group of the same species living and interacting within a community?

  10. A habitat is

  11. What is the area and conditions in which you find an organism ?

  12. A ___ is a type of habitat that exists on a very small scale.

  13. What is a microhabitat?

  14. A niche is

  15. What is an organisms role in its habitat?

  16. 71% of earth’s surface is covered by this type of ecosystem

  17. What is a neuston ecosystem?

  18. The reason that most productive marine ecosystems are found in cold, temperate regions…

  19. What are more abundant nutrients?

  20. The two factors that may account for low productivity in the neuston ecosystem are called

  21. What are photoinhibition and pollution?

  22. These organisms are 10,000 times more numerous in the top few millimeters of water.

  23. What are cyanophytes, diatoms, and dinoflagellates?

  24. This phenomenon brings nutrients up from the seafloor.

  25. What is upwelling?

  26. This ecosystem acts as nurseries for about 75% of commercial fish species

  27. What are estuaries?

  28. These two characteristics make mangroves an excellent ecosystem.

  29. Strong tangled roots that provide habitats and the ability to hold soil in storm surges, waves, and weather.

  30. Adaptations that allow halophytes to survive in salt water include

  31. Stomata, salt glands, and sacrificial leaves

  32. Hunting sea otters disrupted the kelp forest ecological balance because

  33. What is the sea otters eat sea urchins which eat kelp?

  34. Threats facing coral ecosystem include

  35. What is global warming, sedimentation, and coral disease

  36. Reduced sunlight and near-freezing water challenge this marine ecosystem

  37. What is the arctic?

  38. The Antarctic seas are some of the most productive marine ecosystems because

  39. What is because of the rich, deep water surfaces to create the largest nutrient-rich area on Earth?

  40. There is no primary productivity in most of the deep ocean because

  41. What is there is no sunlight?

  42. Most of the deep ocean gets its nutrients from

  43. What is Marine snow?

  44. A place where dead whale rests on the deep ocean floor is called

  45. What is whale fall?

  46. These plants live entirely under water, can live in deep water, and have the same internal salinity as seawater.

  47. What are seagrasses?

  48. The two primary types of organisms found in the abyssal zone are called

  49. What are echinoderms and meiofauna?

  50. This occurs during the 2nd stage of a whale fall ecosystem
