Show Answers:

  1. What is the Biodiversity the same as?
    An aquatic biodiversity is equal to the biodiversity of a Tropical Rainforest.
  2. How are Coral Reefs formed?
    They are formed by Polyp secretions of CaCO2
  3. What are important ecological services of a coral reef?
    Important ecological services are that coral reefs moderate the temperature through CO2 , as well as act as a natural barrier protecting the coast from erosion, and provide a habitat for all the different fishes in the ecosystem.
  4. What are important economic services of a coral reef?
    Some economic services consist of supporting fishing and tourism, providing jobs and building materials, and and increasing studies and are just amazing and enjoyable.
  5. Coral Reefs provide a habitat for ___ opf all the marine organisms.
    1/4 , 25%, .25
  6. Whats causes degradation or a decline in coral reefs?
    Costal development ( because of the increase in population and the land near it is the best [ex: California]), Pollution (due to the increase in population and buildings/homes), overfishing, warmer ocean temperatures leading to Coral Bleaching (the loss in color and a decline in the coral reef health)
  7. Both Salt Water and Fresh Water covers almost ___ of the earth.
    3/4 , 75%, or .75
  8. what are the 5 key factors of determining biodiversity?
    Temperature, dissolved oxygen, food, light and nutrients.
  9. What are the 4 salt water bodies? (ocean or Lakes)
    Atlantic, Pacific, Arctic, and Indian.
  10. What is the biggest body of Salt water that consists of 1/2 of the earths water and covers 1/3 of the earths surface?
    The Pacific Ocean.
  11. What are Aquatic life zones equivalent to ?
    Aquatic life zones are equivalent to  Terrestrial Boimes.
  12. What are the 4 Salt Water life zones?
    The Ocean/Esturaries, the Coastland/Shorelines, the coral refs, and the Mangrove forest.
  13. What are the 3 Fresh Water life zones?
    Lakes, Rivers/Streams, and inland wetland.
  14. Where are the Mangrove forest and the Coral Reef typically located?
    The Mangrove forest and the Coral Reef are typically located around the Equator.
  15. ___% of the earth is Salt Water.
  16. ___% of the earth is Fresh Water.
  17. What is the other 26.8% of the earth?
  18. What is Plankton?
    Free floating.
  19. What are the 3 types of Plankton?
    Phytoplankton, zooplankton,and ultraplankton.
  20. What is Phytoplankton?
    a drifting plant, and alot of algae.
  21. What is Zooplankton?
    a drifting animal and it can be either a primary consumer (because it eats phytoplankton) or a secondary consumer (because it can eat its own kind).
  22. What is Ultraplankton?
    It is extremely small, its a photosynthetic bacteria, and is responsible for 70% of the primary productivity near the earths surface.
  23. What is Nekton?
    They're strong swimmers.

    Ex:) Turtle, fish, and whales
  24. What is Benthos?
    They're bottom dwellers.

    Ex:) Oyster and lobster
  25. What is a decomposer?
    Made up of mostly bacteria and it breaks up organisms to use it as organic matter.
  26. Estuaries, Coast lands, Rivers and Streams are all examples of what?
    Aquatic Life Zones.
  27. What is Turbid/Turbidity?
    • The cloudiness of water.
  28. What are the main ecoclogical sevices that a Marine system provide?
    • Absorption of CO,reduction of storm impact (Mangrove, Barrier Islands, Costal Wetlands), Habitat and nursery areas, scientific information.
  29. What are the main Economic Services does the Marine System provide?
    Food, pharmaceutical, Animal and pet feed, recreation, employment and building materials.
  30. Whats are some highly productive estuaries and Wetlands?
    River mouths, Inlets, Bays, Sounds, Salt Marshes, and Mangrove forest.
  31. What is a Sound ?
    A sound is a lagoon or harbor.
  32. Where are Mangrove Forest located?
    On the coastline in the tropical region.
  33. What do Seagrass Beds produce?
    They support a variety of marine species, stabilize shore lines and reduce wave impacts.
  34. Why is Seagrass important?
    They filter water by sucking up the contaminants such as toxins, excess plant nutrients, and sediments.
  35. What Saltwater life zone has a lot of turbidity?
    • The Estuary.
  36. what does the first sand dune serve to do?

    It serves to act as a barrier and as a storm surge.
