1. Key Ideas

Animals need useful materials from food just as they need gases and water. This lesson explains why nutrients matter, what the digestive system does at Stage 4 level, and how digestion and absorption connect to body needs.

  • animals need nutrients from food
  • food must be processed before useful materials can support cells

2. Success Criteria

By the end, you should be able to:

  • animals need nutrients from food
  • the digestive system has the role of breaking food down
  • absorption links food to body use

3. Key Terms

NutrientsUseful substances obtained from food that the body needs.
Digestive systemThe body system that breaks food down so useful materials can be taken in.
DigestionThe process of breaking food down into smaller usable parts.
AbsorptionThe movement of useful materials into the body after digestion.
FoodA source of materials and energy for living things.
Body needsThe materials cells need in order to function and survive.
