Make a generalized diagram that shows the different components of an aquatic food web highlighting how energy would flow through the system. If a toxic chemical were introduced to "producers" that accumulates in the bodies of all organisms, which trophic level will be most affected
During this lab you surveyed at least 3 ponds - the Library pond, Hennington pond and Nature Preserve pond. How would pH and dissolved oxygen change over the course of a day (morning, noon, and night)? Why do you think this would happen? Would it change over the course of a year? If yes, why do you think it would change? If no, why do you think it would not change? What do you think is driving changes and aquatic pH and dissolved oxygen levels?

3. Levels of organic wastes from manmade sources such as food-processing plants, run-off from the lawn, and wastewater treatment bring a lot of organic material to the aquatic ecosystems favoring the oxidation of organic compounds. What would happen to the dissolved oxygen and pH in the ponds or lakes if a large amount of wastewater is added to these systems? What cascading effects may these changes in dissolved oxygen and pH have?

4. During this lab you surveyed at least 3 ponds - the Library pond, Hennington pond and Nature Preserve pond. Which one would likely support the highest level of biodiversity? What features of this pond makes it suitable for maintaining high levels of biodiversity?

5. During this lab you surveyed at least 3 ponds - the Library pond, Hennington pond and Nature Preserve pond. What ecosystem goods and services does each of the ponds you sampled today provide FIU as an institution? Do any of them benefit you personally? Name one other Florida ecosystem and describe 2 goods or services it provides the south Florida population
