Question

hen hen the 75. For measurements of primary productivity, the light bottles are used to measure: is: A stand A tidal An El A dee a. respiration b. net photosynthesis c. gross photosynthesis d. secondary production 76. Growth rates of microbial populations are best described by: a. linear functions b. stepwise functions c. biphasic functions d. exponential functions doesn it do bec d. ber 77. Photosynthetic rates in the euphotic zone vary as a function of a. respiration rates b. oxygen concentrations c. light concentrations d. carbon concentrations b. lulton that are herhivores feed primarily on

Explanation / Answer

75. b. net photosynthesis. In the light bottles, both respiration and photosynthesis will be occurring simultaneously. And the total photosynthesis minus respiration will give net photosynthesis

76. d. exponential function. Growth rate of microbial population undergoes exponential function.

77. c. light concentration. As the amount of light decreases the rate of photosysthesis decreases.
