Textbook Question
Chapter 54.2, Problem 4CC
MAKE CONNECTIONS Ø Rising atmospheric CO2, levels lead to ocean acidification (see Figure 3.12) and higher ocean temperatures, both of which can reduce krill abundance. Predict how a drop in krill abundance might affect other organisms in the food web shown in Figure 54.15. Which organisms are particularly at risk? Explain.

O the global CO2 concentration remain stable throughout the year the CO2 concentration in the southern and northern hemisphere cycle at the same time of the year O the CO2 concentration has larger annual fluctuations in the southern hemisphere because of the larger ocean area O the CO, concentration has larger annual fluctuations in the northern hemisphere because of the larger land area A Moving to another question will save this response.arrow_forward
- The figure above shows main abiotic and biotic factors influencing the physiology and behavior of fish larvae in estuaries. The more important the factors are for the larvae, the thicker the lines. Suppose changes from question 1 take place. Draw a new figure and redefine the thickness of the lines and new factor interactions. This is from question 1 : A proposal is made to deepen the entrance and main channel of an estuary. What do you suppose will happen to the salt marshes that surround the channel? What do you predict will happen to the productivity of the estuary? Deeper channels would probably change the mixing of the fresh and saltwater and lead to increased salinity and changes in the salt wedges in the channel. This would probably negatively impact the plants on the edges of the channel, as they would have to deal with higher salt levels than they are adapted to. The strain that would be put on the plants (like cordgrasses) in the marshes, would most likely lead to a…arrow_forwardThank youarrow_forwardThe overexploitation of cod in the North Atlantic releases crab and shrimp from predation pressure and results in a boom in the number of crab and shrimp.
