If a grass starts with 30,000 kJ of energy, a cheetah that ate a zebra that consumed the grass would acquire 300 kJ of energy.
In the food chain, only about 10% of the energy in one trophic level moves to the next while the rest is lost as heat.
Thus, the zebra would only acquire 10% of the energy in the grass:
10/100 x 30,000 = 3,000 kJ
The cheetah, in turn, will only be able to acquire only 10% of the energy in the zebra:
10/1000 x 3,000 = 300 kJ
Thus, the total energy accruable to the cheetah from the zebra is 300 kJ.
