A tree like we used to have would celebrate the past.

But trees also use a lot of water and nutrients.

Until the 1950s, trees used to exist by the square.

A big tree can use several hundred gallons of water a day.

You're told you have to build a picture of a tree using the squares exactly as they are.

Plants and trees use the soil to hold them upright.

Maybe I'm missing something, but this tree could use a makeover.

Old trees also use less water for growth than young trees do.

"The average large tree uses 1,200 gallons of water a day and it's not there."

In this case, C4.5 creates a decision node higher up the tree using the expected value of the class.
