Which of these statements describes an accurate model for how carbon dioxide and oxygen levels change within the ocean over time? Choose two answers that apply.
A) eutrophication of the ocean leads to an increase in dissolved oxygen.
B) photosynthesis by the phytoplankton increase the oxygen concentration of the ocean.
C) decomposition of dead organic matter decreases the oxygen concentration in the ocean.
D) cellular respiration by primary consumers increases the oxygen concentration in the ocean
E) anaerobic respiration at the ocean floor decreases the carbon dioxide levels in the ocean
The unicellular cyanobacterium Prochlorococcus sp. is the most abundant photosynthetic microbe in tropical and subtropical oceans. At least two ecotypes exist: one is adapted to high light and the other to lower light intensities. How does the presence of these two ecotypes contribute to their physiological success and their numerical success? How would you determine the amount of fixed carbon they contribute to these open-ocean ecosystems?
In a shallow coastal ecosystem dominated by seagrasses, nutrient limit primary production under low nutrient ( oligrtropihc) conditions while light becomes the limiting factor under high nutrient ( eutrophic) condition. In the conceptual model given explain why sea grasses, macroalgae and poluplantkon are in the position of the graph. Kindly explain your answer
