Chapter 13 1) In primary production: animals make Proteins. Plants utilize oxygen. There is a net gain in organic carbon by organisms. Oxygen utilized by animals is less than the oxygen consumed by autotrophs. Carbon dioxide is released into the water. There is a net gain in organic carbon by organisms. 2) In general, the rate at which energy is stored by organisms through the formation of organic matter is called: Primary productivity 3) The depth at which the cellular respiration rate equals the photosynthetic rate is referred to as the: Compensation depth for photosynthesis. 4) The color of light most readily absorbed by water is ___. Red 5) Mass mortality events of marine mammals and birds may occur after ingesting prey items that contain algal toxins. What organism that can cause harmful algal blooms should humans be concerned about if animals in the area are having seizures and exhibiting erratic, "drunken-like" behavior?
Pseudo-nitzschia, because it causes amnesic shellfish poisoning. 6) Diatoms, important producers in the epipelagic open ocean, are members of the Division: Chlorophyta. 7) Important marine autotrophs that have silica incorporated into their cell walls are: Diatoms 8) C. Sargassum (Gulf weed) 9) In dead zones resulting from eutrophication, animal life is absent due to the lack of _________. Nitrates 10) Of the following types of organisms, which are examples of microscopic algae? Dinoflagellates, Diatoms 11) The percentage of biomass regularly decomposed within the euphotic zone is about: 90% 12) The relative productivity in the world's oceans from most productive too least productive is:
Temperate waters, polar waters, tropical waters. 13) Productivity in polar oceans is: light-limited 14) Although primary productivity in tropical areas is generally low, which of the following tropical locations have unusually high primary productivity rates? All the above tropical areas have relatively high primary productivity.
