Because of an Acorn by Lola and Adam Schaefer (Chronicle Books, 2016; illustrated by Fran Preston-Gannon) has pretty pictures and simple text to show the connection between an acorn growing and the other types of life surrounding it. Birds, fruit, deer, chipmunks, and other animals all are able to live. They also contribute to adding more acorns, thus creating a forest.
Much of the connection of the growing ecosystem is told within the lovely illustrations. The pages have cause and effect phrases such as this: “Because of an acorn, a tree.” The incomplete sentence format simplifies this concept to even younger audience, making it an easily accessible read aloud book for youngest learners.
