"If asked to define a forest, students might say, it has a lot of trees. But many places have a lot of trees. So, what makes a forest a forest? Students learn that a forest is unlike any other biome on Earth. And a temperate forest is even more specific. Students learn the many life cycles found within a forest and how the energy pyramid explains the numbers of forest plants and animals. In addition, students learn by examining how forces usually considered destructive work to help forests survive." -- Publisher website.
