If the flowers contain 30,000 kcal of energy, how much energy will the jackal obtain from eating the roadrunner?

The food chain would be:

Flower --> Roadrunner --> Jackal

We know that the amount of energy passed from one tropic level to a higher one is 10. Therefore:

Energy of Roadrunner = 0.10 *30,000 kcal = 3,000 kcal

Energy of Jackal = 0.10 * 3,000 kcal = 300 kcal (ANSWER)

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
