People who own cows and other animals that eat grasses create plans to move these animals over time. They move the animals from one area to another so they can eat grasses in different places. This allows grasses to continue to grow. Why is it important to have a plan for grazing animals that allows grasses to grow in a healthy way?

• It causes soil erosion and allows for planting of new species.

• It prevents the dispersal of seeds and the overgrowth of plants.

• It protects the predators in an area by providing plants to eat.

• It protects the soil so plants will continue to grow; food will be available for herbivores.
