Record 5 data points for the Oxygen Percent Concentration time period Record your oxygen concentration points below If possible get a wide range of percentages Date Collected Oxygen Pet Sat Depth 31 Jan 24 Feb 24 8 6 3 0 31 Jan 24 Why is it important to have data that is collected at similar times es The data might be different at different dimes or the year due to deciden other charges etc windo 2751 Do you think depth makes a difference in the oxygen percent concentration Or is depth not a factor in oxygen percent concentration Explain your reasoning using evidence from your data collection if possible 3F1 duo because when the oxygen was at 8 6 the depth was orisen was 7 3 the depth was 33 t then 0 lured 3 01 depth was 66 Ft meaning that no Predict the correlation between oxygen percent concentration and the urchin population Read through the article titled Water quality requirements for culture of the green sea urchin What happens to urchins if the oxygen percent concentration drops too low for an extended period of time What else do you think may occur in the ecosystem because the oxygen percent concentration is too low Connection to the ecosystem Think back to what you have learned about trophic levels keystone species and food webs chains and pyramids All species are equal but some are more equal than others If urchins were wiped from the ecosystem what effect would this have on the kelp community What other effects would this have on the ecosystem as a whole What impact would that have on other spesia
