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? Use the 10% rule.
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. Figure 1 of 1 Part A 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 4.00 g of fat to fly over a distance do without stopping for…

How does the kinetic energy used to help the ecosystem of a hospital operates? And what are the “path”(transformation ) it will have to take from its source to be useful in the ecosystem of the hospital?
The “biological capacity” is the ability of the natural world to replenish its renewable resources and absorb the resulting waste products and pollution. Exceeding the biological capacity creates an “ecological deficit.” Discuss the potential future implications for the earth resulting from the fact that we are currently exceeding the earth’s biological capacity by about 50 percent
