  • What is Nekton?
    able to swim against ocean currents
  •  15
  • What is Benthic?
    describing organisms that live on the bottom of the ocean
  •  15
  • What is Detritus?
    dead organic matter and the decomposing "organisms" that live among it (p252)
  •  15
  • What is aphotic?
    area where no light reaches, therefor no photosynthesis can occur.
  •  15

    an organism that lives in the water column

  • What is Ecology?
    the study of relationship between an organism and its environment

    a factor required for a population to grow but present in small quantities in an ecosystem
  •  15
  • What is Productivity?
    the rate of photosynthesis carried on in an ecosystem, minus the rate of respiration of the photosynthetic organisms

  • The population of a certain fish is noted to decrease even though the birth rate appears to be the same.  What abiotic factors might cause this?  What biotic factors might cause this?
    A- salinity, dissolved CO2 (affecting food source)water temperature, B-parasites, predators,

  • Is there an aphotic zone on the continental shelf?
    Yes the outer shelf.

  • List and describe the habitat regions of the ocean discussed in this module. (6 zones)
    Splash zone-never under water,intertidal zone,inner shelf(photic),outer shelf,bathyal zone(aphotic),abbysal,hadal always under water.

  • Can one habitat be affected by another habitat? Give an example?
    River delta is affected by rain in the mountains. Sunlight blocked by a highrise building will affect the coral growth near the shore.

  • What happens if there is not enough of the kind of bacteria that do denitrification in a fish tank?
    This kind of bacteria converts ammonia into gaseous nitrogen, so the ammonia levels will rise.

  • How does photosynthesis participate in Carbon fixing?
    It uses CO2 and creates sugars.
