National Science Education Standards Organisms have basic needs. For example, animals need air, water, nutrients, and light. Organisms can survive only in environments in which their needs can be met. The world has many different environments, and distinct environments support the life of different types of organisms. (Page 129) All animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat plants. (Page 129) |
Benchmarks Plants and animals both need to take in water, and animals need to take in food. In addition, plants need light. (Page 119) Many materials can be recycled and used again, sometimes in different forms. (Page 119) |
