Small birds like that in (Figure 1) can migrate over long
distances without feeding, storing energy mostly as fat
rather than carbohydrate. Fat is a good form of energy
storage because it provides the most energy per unit
mass: 1.00 grams of fat provides about 9.40 (food)
Calories, compared to 4.20 (food) Calories per 1.00
grams of carbohydrate. Remember that Calories
associated with food, which are always capitalized, are
not exactly the same as calories used in physics or
chemistry, even though they have the same name. More
specifically, one food Calorie is equal to 1000 calories of
mechanical work or 4184 joules. Therefore, in this
problem use the conversion factor 1 Cal = 4184 J.

Consider a bird that flies at an average speed of 10.7 m/s and releases energy from its body fat reserves at an
average rate of 3.70 W (this rate represents the power consumption of the bird). Assume that the bird consumes

- You are studying a woodland ecosystem with four trophic levels. For simplicity, let's that say the system only consists of chipmunks which eat plants, snakes which eat the chipmunks, and hawks which eat the snakes. The plants produce 5,550,000 kcal of energy, the chipmunks have 780,000 kcal of energy available, and the snakes have 48,000 kcal of energy available. If each hawk needs 200 kcal of energy on average, how many hawks can this ecosystem support?
