In Needs of Plants and Animals students explore the phenomenon that all animals need food to live and grow and that all animals obtain their food from plants or other animals. Students also come to understand that plants need air, water, and light to live and grow and that living things need water, air, and resources from the land and that they live in places that have the things they need. Humans use natural resources for everything they do. Students describe the needs of plants and animals and their relationship with the local habitat as well as identify ways landscapes can be transformed into a habitat for plants and animals.
