What happens to the dissolved oxygen (the oxygen that is in the water) between May 1st and 15th based on the data in Figure 1.
Phytoplankton carry out photosynthesis. Each phytoplankton only lives a few days. Based on the life cycle and other information about phytoplankton, what do you think happened to the phytoplankton population in May?
How is the phytoplankton population related to the oxygen concentration in Figure 1 (see the graph)?
Phytoplankton are plant like organisms that have a chloroplast.
Describe what is happening to dissolved oxygen (oxygen in the water) between May 15th and 31st, based on the data in Figure 2.
From May 15 to May 31, the number of consumers and decomposers increased. What do you think would happen to the concentration of carbon dioxide in the water.
Make your model below OR make your model on paper.
What do you think would happen to the concentration of carbon dioxide in the water during the same time period, May 1-15?
Consumers and decomposers that eat the phytoplankton are also present In the Gulf of Mexico. As the phytoplankton population increases, so do the populations of consumers and decomposers. How might the presence of increased numbers of consumers and decomposers help explain the decrease in the oxygen concentration?
