Two different species of catfish, Twig and Bristlenose, eat algae. Both species take in 4000 J of energy from eating algae. Both excrete 2500 J of feces, but Twig catfish live in a high current area where they need to expend more energy because they are swimming. Therefore, it takes this catfish 1250 J of energy for respiration, and they only can add 250 J towards growth. Bristlenose catfish live in a calm lake where they do not swim as much and can use more of their food towards growth, specifically 350 J. What is the production efficiency of each fish?
