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 clover plants, per day, does it take to support one hawk?
approximately 600 clover plants
approximately 30 clover plants
approximately 60 clover plants
approximately 3 clover plants
None, clover plants do not support hawks.
I found this---- but not sure if it relates to Hawk needs 300 calories from eating rabbits, so needs 3,000 rabbit calories available since only 10% moves up the food chain. 3,000 rabbit calories (where food energy is 500 calories per rabbit) means you need 6 rabbits to feed the hawk.
The energy transfer between trophic levels is usually around 10%. To support one hawk, you would need to consider the calorie requirements for each species in the food chain.
1. A hawk needs 300 calories per day. Since only 10% of energy is transferred between levels, it needs 3,000 rabbit calories (300 / 0.10 = 3,000).
2. Rabbits have 500 calories each. You need 6 rabbits to provide the necessary calories to the hawk (3,000 / 500 = 6).
3. Each rabbit needs 100 calories per day. To support the 6 rabbits, you need a total of 600 calories from clover (6 * 100 = 600).
4. Clover plants have 10 calories each. So, you need 60 clover plants to support the 6 rabbits (600 / 10 = 60).
Therefore, it takes approximately 60 clover plants per day to support one hawk.
To calculate the number of clover plants needed to support one hawk, we need to consider the energy transfer between the different trophic levels in the food chain.
First, let's calculate the total calorie requirement for the hawk, which is 300 calories per day.
Next, we need to consider the energy transfer efficiency between trophic levels. Typically, only about 10% of energy is transferred from one trophic level to the next.
Since the hawk requires 300 calories, we need to determine how many calories are needed at the lower trophic levels to support this energy requirement.
Given that only 10% of the energy is transferred from one trophic level to the next, we can calculate the total energy required at the lower trophic levels.
For example, if the hawk requires 300 calories, we can divide this by 10% to determine how many calories are needed at the rabbit level.
300 calories / 10% = 3000 calories
Since each rabbit contains 500 calories, we can divide the total energy needed by the energy content of each rabbit.
3000 calories / 500 calories = 6 rabbits
So, it would take approximately 6 rabbits to provide enough energy to support one hawk.
Since clover is at the base of the food chain and does not directly support the hawk, the answer is none.
To determine how many clover plants are needed to support one hawk, we need to consider the flow of energy through the food chain.
First, let's calculate the energy required by a hawk in a day, which is 300 calories.
As you correctly pointed out, only 10% of the energy available at each trophic level moves up to the next level. This means that for the hawk to receive 300 calories, there must be 10 times more available energy at the rabbit level.
So, the hawk needs 300 calories, which is 10% of the energy available at the rabbit level. This means the rabbits collectively need to have 10 * 300 = 3000 calories available.
Since each rabbit contains 500 calories, we can find out how many rabbits are required by dividing the total required calories by the calories in each rabbit: 3000 / 500 = 6 rabbits.
Now, to calculate the number of clover plants required, we need to consider the energy flow from the clover to the rabbit. Each clover plant contains 10 calories, and since only 10% of the energy moves up to the next level, we need 10 times more energy at the clover level compared to the rabbit level.
Therefore, the total energy required by the rabbits would be 10 * 3000 = 30,000 calories. As each clover plant contains 10 calories, the number of clover plants required would be 30,000 / 10 = 3000 plants.
So, to support one hawk, it would take approximately 3000 clover plants per day.
Therefore, the closest answer choice is "approximately 3000 clover plants."
