Barnacles and mussel distribution b. Chemical composition of the rocks along the seashore c. Salinity, temperature, and exposure tolerances and biotic interactions d. Sunlight 52. The abundance of viruses in the ocean is approximately: a. b. c. d. e. They don't exist in the ocean About 1,000 viruses per milliliter About 100,000 viruses per milliliter About 1,000,000 viruses per milliliter About 10,000,000 viruses per milliliter 53.

Biodiversity describes: a. b. c. d. The range of habitats available in a specific area where a population lives. The number of niches available in any one habitat. The variety of organisms or species present in a community. The number of individuals in a community 55. Symptoms of coastal eutrophication include: a. b. c. d. e. Fish kills caused by toxic substances Anoxic 'dead' zones in deep water Poor light penetration Low diversity of the phytoplankton community All are correct True or False. Because of their large size, marine mammals make up the bulk of the living biomass in the sea What do I mean by this? a. b, c. d. Only 10% of each trophic level is consumed. 10% of the food each organism eats is excreted. Only 10% of what is eaten is converted into biomass at the next trophic level. Organisms eat only 10% of the available food. 58. Vertical nutrient distributions in the ocean can best be described as having: a. Conservative distributions b. Constant distributions c. Redox sensitive distributions d. Random distibutions e. Non-conservative distributionsExplanation / Answer
50. C is correct.
The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.
51. Zonation in rocky intertidal communities is determined by the temperature, Exposure tolerence etc. OPtion C is corect.
52. Option E is correct As about 10 millions of viruses are there is 1ml of ocean water.
53. 1,000,000 bacteria per milliliter (1/5 of a teaspoon) of water is approximately the coastal ocean. OPtion D is correct
