Check my work Part 1 of 5 Required information Small animals eat much more food per kilogram of body mass than do larger animals. The basal metabolic rate (BMR) is the minimal energy intake necessary to sustain life in a state of complete inactivity. The table lists the BMR in kilocalories per day, the mass, and the surface area for 4 animals. 10 points Animal Mass (kg) eBook BMR (kcal/d) 3.80 770.0 2050 4900 Mouse Dog Human Horse 0.0300 110.5 78.9 Surface Area (m2) 0.00320 0.720 1.80 Hint Print 440 5.70 References What is the BMR per kilogram of body mass for the mouse? O kcal/d/kg

Answer 1

(i) BMR per kilogram of body mass for the Mouse = (3.80 kcal/d)/0.0300 Kg = 126.67 kcal/d/Kg

(ii) BMR per kilogram of body mass for the Dog = (770.0 kcal/d)/(10.5 Kg) = 73.33 kcal/d/Kg

(iii) BMR per kilogram of body mass for the Human = (2050 kcal/d)/(78.9 Kg) = 25.98 kcal/d/Kg

(iv) BMR per kilogram of body mass for the Horse = (4900 kcal/d)/(440 Kg) = 11.14 kcal/d/Kg
