Question

The American black bear (Ursus americanus) relies on burning or catabolizing fat during hibernation to meet metabolic demands – a period when the animal does not actively forage for food. Assuming the black bear will starve once its fat stores are gone, how many days can a black bear with 10 kg of fat stores survive if it burns 0.0602 g of fat per minute? Report your answer as three significant figures.

Answer 1

Ans stored fat amount = 10 kg or 10 x 100 = 10000 gm Rate of fat burning = 0.0602 gm/min Total time (in min.) to consume total stored fat = 10,000 = 1,66, 112.957 minutes 0.0609 - 1,6 converting into days - i 1 minute = 0.00069 4 4 4 4 day . 166112.957 minutes = 166112.95780.000694444 = 115.356 days approx, Ans. : - Bear will survive for 115.356 days approx.
