Consider the following food chain: hawk - rabbit - clover. Each species will contain a different amount of calories in its body (clover: 10 calories, rabbit: 500 and hawk: 1200). Each species has a different daily caloric requirement (clover: sunlight, rabbit: 100 calories, hawk: 300).
How many rabbits, per day, does it take to support the hawk?
approximately 6
about 1/2 a rabbit
2 whole rabbits
12 rabbits
2 whole rabbits?????
To determine how many rabbits it takes to support the hawk, we need to calculate the calories consumed by the hawk and compare it to the calories contained in a rabbit.
The hawk requires 300 calories per day.
A rabbit contains 500 calories.
To find out how many rabbits the hawk needs, we can divide the hawk's caloric requirement by the calories in a rabbit:
300 calories / 500 calories = 0.6
Therefore, it takes approximately 0.6 (or about 6/10) of a rabbit to support the hawk.
So the answer is approximately 6 rabbits per day.
To find out how many rabbits per day it takes to support the hawk, we need to consider the caloric requirements of each species in the food chain.
First, let's determine the energy flow in the food chain. The clover gets its energy from sunlight, and it has 10 calories. The rabbit then consumes the clover, obtaining 500 calories of energy. Finally, the hawk consumes the rabbit, gaining 1200 calories of energy.
Now, let's compare the caloric requirement of the hawk (300 calories) to the calories obtained from the rabbit (1200 calories). To support the hawk, the number of rabbits required per day can be calculated as follows:
Number of rabbits = Calories required by hawk / Calories obtained from one rabbit
Number of rabbits = 300 calories / 500 calories
Simplifying the equation, we have:
Number of rabbits ≈ 0.6
So, it takes approximately 0.6 (or about 6/10) of a rabbit per day to support the hawk.
Therefore, the closest answer choice is "approximately 6 rabbits."
