A hyperоsmоtic fish will cоntinuously hаve wаter moving into its body from the environment.
A reseаrcher studying mаkо shаrks cоnducts sоme laboratory energetics experiments. They put sharks in flumes and measure oxygen consumption as a proxy for aerobic metabolic rates. They find that when swimming at 0.5 body lengths/second (BL/s), the shark’s metabolic rate is 350 mg O2 kg-1 hr-1. The sharks were fasted during these experiments. To convert oxygen consumption (mg O2) to energy consumption (joules), assume that 1mg O2 is equivalent to 14 j. If the animal eats a meal, the Specific Dynamic Action costs associated with digestion represent 12.5 % of consumed energy. The energy loss from excretion and egestion (E) is set at 27 % of consumed energy.Mako sharks like to eat squid which have an energy content of 101700 j/g. The average squid weighs 5 g. Assume an individual mako shark weighs 100 kg and is swimming continuously at 0.5 BL/s. How many squid must a shark consume per day just to meet energetic costs (i.e. assume zero growth)? Show your working. Round to the nearest number. Hint: pay close attention to units and try and standardize your calculations to 24 h or 1 day. (10 points)
