Water help

I have a question i have to do for chemistry and i dont have any clue on what its talking about. Can someone fill me in a little? I'm not asking for the answer, just help on understanding it.

It requires 120 L of water to to produce a 1.3 L can of juice and it takes about 450 L of water to place a single egg on your breakfast plate. What explanation can you give for these two statements?

never mind, i figured it out.

you have to feed the chickens and water the fruit tree ?

That answer is wrong. It takes 100 L to grow the fruit tree. The workers that pick the fruit consume 5 liters, the driver that drives the fruit to the factory consumes 5 liters, the grocery store workers consume 9 liters and you need 1 liter of water to mix the .3 L of concentrate with.
