"Trees" Natural Recordings by Native Speakers
A tree is a perennial plant with an elongated stem, or trunk, that supports branches and leaves in most species. Trees have several important characteristics:
1. Height: Trees have a single main stem called a trunk, which is the main vertical stem of a tree.
2. Roots: The roots of a tree are the structures that grow under the ground and they hold the tree in place, also serving to absorb essential nutrients from the soil.
Many animals, like bears, live in and around trees. Trees are an essential source of oxygen, shelter, food, and other resources for various animals.
