All the food we eat in one day has the same energy?

One litre of petrol

1/2 litre of petrol

1/3 litre of petrol

1/4 litre of petrol

The average daily human energy intake is roughly 2000-2500 kilocalories.

One liter of petrol contains approximately 34.2 Megajoules (MJ) of energy, equivalent to roughly 8342 kilocalories.

Therefore, 1/4 liter of petrol has about 8.55 MJ of energy, which is closer to the daily human energy needs than the other options.
