Question

If the total amount of energy in the producer level ecosystem is 40,000 kilocalories how much energy is available for the first level consumers?

Answer 1

Answer:- 4,000 kilo-calories.

Step-to-step-explanation:-

We know that the ten percent rule says that when energy is passed in an ecosystem from one tropic level to the next then only ten percent of the energy will be passed on.

Given: The total amount of energy in the producer level ecosystem = 40,000 kilo-calories.

Then, the amount of energy in the first level = [10% of 40,000] kilo-calories.

⇒ The amount of energy in the first level =
`0.01*40,000` kilo-calories.

⇒ The amount of energy in the first level = 4,000 kilo-calories.

Answer 2

Each level causes a loss of 90 percent of the overall total due to the production of heat and energy. In this case, with 40,000 kcal available from the producers, this would cause (40,000 * 0.90), or 36,000 kcal to be lost. (40,000 - 36,000) = 4,000 kcal will be available to the first-level consumers in this ecosystem.
