1. Grasses: Grasses are herbaceous plants that typically have slender leaves and grow in tufts or clumps. They are an important food source for many animals, including herbivores and granivores. Grasses also help to hold soil in place, preventing erosion.
2. Trees: Trees are woody plants that typically have a single trunk and branches. They provide shade and shelter for animals, and their leaves are a food source for many herbivores. Trees also produce oxygen and absorb carbon dioxide, helping to regulate the climate.
3. Shrubs: Shrubs are woody plants that have multiple stems and typically grow lower to the ground than trees. They provide cover for animals and food for birds and other animals. Shrubs can also help to control erosion and provide windbreaks.
