Now go and look at a plant you can see.
Where does it get its water from?
Where does its light come from?
Draw the plant you looked at.
Use a real plant. Tick each box when he can point to where it gets that thing.
Choose an animal. Draw where it lives, and what it eats.
Which one of the four is the odd one out?
Food is the odd one out: a plant makes its own from light.
