Question

A service ice storm occurs just as the sun is rising on Monday December 1. Small passerines are unable to peck through the ice for their food. A chickadee that weighs 14 g has 1 g of surplus body fat on Monday at sunrise (8am) and will not be able to feed until the ice melts at 8 am on tuesday. assume that 1) there are 8hrs of daylight (8am to to pm) and 16hrs of darkness (4pm to 8am), 2) the daytime metabolic rate is 2 times BMR (BMR = 140X^.70, X = weight in kg and BMR = kcal/day) and night time metabolic rate is BMR (BMR = 115X^.73, X= weight in kg and BMR = kcal/day) for those respective hours, and 3) surplus body fat is the only source of available energy. Here are the following questions:      Show calculations

A) Will the chickadee survive until Tuesday Morning (i.e will all the surplus body fat be gone)?

B) If it dies when does it die?

C) if it lives how much surplus energy does it have at 8 AM tuesday and how much longer could it survive if the ice did not melt?

I need help with how to do calculations to get these answers              

Explanation / Answer

Use the BMR equation for males. For men, the equation for calculating BMR is: BMR = 66 + (13.8 x weight in kg.) + (5 x height in cm) - (6.8 x age in years). This simple equation takes into account your height, weight, age, and sex. BMR increases with height and weight but decreases with age.

Use the BMR equations for females. Because women often (but not always) have less lean body mass (found by subtracting the mass of fat tissue in the body from the total mass of the body) than men, they will generally have lower BMRs. The BMR equation for females takes this into account - it multiplies height and weight by smaller values. However, since women's metabolisms slow less drastically with age than men's, the value that age is multiplied by is also smaller. For women, the BMR equation is: BMR = 655 + (9.6 x weight in kg.) + (1.8 x height in cm) - (4.7 x age in years).
