 Animal Typical Food (a) Suggest what might be a typical food for each of the four animals named in the table above Gnu= Elephant= Cheetah= Hyena= (b) The Gnu actually spends 16h per day eat and chewing its food. What is happening during the 7h not shown in the table? (c) What percentage of its body mass is eaten by (i) the elephant and (ii) the cheetah with each meal? Use the following equation: mass of food x 100 mass of the animal or the mass of food (kg) multiplied by 100 and the result divided by the mass of the animal (kg). The answer is a percentage. (i) elephant Space for calculation Answer: (ii) cheetah Space for calculation Answer: (d) Why are the cheetah and hyena able to eat their food quickly, but the elephant and the gnu spend a long time chewing their food?
