always clean and fresh.

help clean the air.

Brian: Sure, Danny! Look, there is an apple tree over there!
Danny: Is there a donut tree
Brian: Donuts don’t grow on trees!
Jenny: Trees and other plants are important to people.

Jenny: The forest is important to animals, too. Many animals live in the
forest and eat the fruit from the trees. They eat other plants, too.

the soil away. Plants also make everything look beautiful.
