the first plants that lived on land were nonvascular plants similar to today’s mosses. Today there are many more vascular plants than nonvascular plants. Explain why vascular plants might be more successful than nonvascular plants.
Nonvascular plants have a poor transportation system. Since they soak up water from the ground if the land is dry they will die. Vascular plants have a more sufficient means of transporting water and minerals. Also unlike vascular plants nonvascular plants have no roots and are damaged easily.

The southern pine beetle damages pine trees all over the southern United States. The female beetle finds a tree, digs holes in the wood, and lay her eggs deep inside the tree. An egg hatches, and the larva eats wood inside the tree. Then it crawls to the wood just under the bark, where it becomes a pupa. Once the pupa turns into a beetle, it crawls out of the tree and flies away. How many stages of the southern pine beetle’s life cycle are spent entirely in a tree?

Plants and animals have adaptations suitable to their environments in which they live. List two ways desert hares and arctic hares differ.

Arctic hares have small ears that help retain heat in their bodies.
