Okay, so imagine there's a tree that grows apples. People like to eat apples because they taste good and are healthy for them. But sometimes, there are problems with the apple tree. Maybe there are bugs eating its leaves or the soil it's planted in isn't good for it.
That's where the apple tree man comes in. He's like a doctor for the tree. He checks on it to see if it's healthy and if it needs anything to help it grow better. He might use special tools to measure the soil or spray something on the leaves to keep the bugs away.
The apple tree man wants the tree to be strong and healthy so that it can grow a lot of apples. That way, people can enjoy them and also the people who take care of the tree can sell them and make some money.
So, think of the apple tree man as a kind helper who makes sure the apple tree is happy and healthy so that it can give us yummy apples to eat.
