- Pond A Pond B at the Pond C Figure 3. Representation of three experimental ponds located in the Hagen Aqualab at the University of Guelph. Ponds have one or both of two fish species: Stripey- Orange Clownfish and Black Herring. All ponds have been kept at 20°C for many years and contain large and small worms as food. True Falce For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. If Pond C is cooled to 10°C and the Stripey-Orange Clownfish die, then 10°C must be below the Stripey-Orange Clownfish's range of tolerance for temperature. △ 英拼Two species of sea urchins live practically side by side on sandy bottoms. The two species appear to have the same diet: drift seaweedsand other bits of organic matter. They are able to live in the sameenvironment with minimal competition. How might they be able toshare their habitat and food resources?Science Name: Date: Class: Range of Tolerance Data Analysis One of the responsibilities of an aquatic biologist is to make sure that the abiotic factors stay wiumh the acceptable ranges for the optimal help for the Species within the local ecosystem. Bcologists, including aquatic biologists, use the range of tolerance to monitor the number of different populations residing in the area. m order to do so they use statistical models. Create a graph displaying on the x-axis the ranges of abiotic conditions such as temperature to study the population of rainbow trout in the area ( use the launch model as an example), Label each interval with temperature range and condition. What Causing Stress in Rainbow Trout Population The optimal range is the amount of an abiotic factor that produces the highest possible population. For water temperature, this would be about 6-10°C. Label this area on the graph. 1. 2. The zone of physiologic stress occurs when an abiotic factor exists at levels that are…

What was the impact of fishers invading the ocean used by other communities? 2 How does this activity relate to real fisheries and ocean issues? 3 What does the following quote mean? "In the end, our society will be defined not only by what we create, but by what we refuse to destroy." - John Sawhill, former President of the Nature Conservancy 4 How does this quote relate to fisheries? 5 What factors have not been included in this activity that impact real fisheries? 6 What happens to a resource when demands are high, so new technologies are introduced to increase efficiency, but the resource is finite? Explain. 7 How can a sustainable fishery be developed? What limitations should exist? How should it be regulated? 8 What are other commonly held resources, besides fisheries? What are issues that surround them? How can they best be managed?Draw a food chain for Puget Sound using these organisms and abiotic components. Some possible organisms to include in the food chain are: herring, marine bacteria, people, phytoplankton, pteropods, krill, oysters, Dungeness crab, salmon, Orcas.
