1. The problem statement, all variables and given/known data
Sun to plant
Worm eating a plant
Bird eating a worm
Human eating a bird
Human throwing a ball up in the air
Plant to coal
Coal to a factory
Factory to power lines
Power lines to computer
Sun to Rubber tree
Rubber tree to factory
Factory to ball (manufacture)

3. The attempt at a solution

Sun to plant - light energy
Worm eating a plant - chemical energy
Bird eating a worm - chemical energy
Human eating a bird - chemical energy
Human throwing a ball up in the air
Plant to coal - chemical energy
Coal to a factory
Factory to power lines
Power lines to computer - electric energy
Sun to Rubber tree - light energy
Rubber tree to factory
Factory to ball (manufacture)

Correct me if I'm wrong on these.

Looks like you have the right idea, but a transfer involves going from one form of energy to the next, so I think you should rephrase your answers in the form of: (starting energy) to (ending energy).

For example, the first one would sound better as: light energy to chemical energy

Oh, thanks. Do you know if the ones i have so far are right? I think these two are chemical, but i may be wrong

Coal to a factory
Factory to power lines

I have no clue about these two

Rubber tree to factory
Factory to ball (manufacture)

With kinds of energy transformations is one familiar?
