- Saprophytes
- Provide examples of animals for each type.
3. **Processes of Nutrition (20 minutes)**
- Use diagrams and the model of the digestive system to explain the stages of nutrition:
- **Ingestion:** Intake of food
- **Digestion:** Breakdown of food into simpler forms
- **Absorption:** Nutrients taken into the blood
- **Assimilation:** Incorporation of nutrients into cells
- **Egestion:** Removal of indigestible parts
- Show a video clip demonstrating digestion in ruminants and non-ruminants, if available.
4. **Balanced Diet and its Importance (10 minutes)**
- Explain what constitutes a balanced diet for animals.
- Discuss the role of carbohydrates, proteins, fats, vitamins, and minerals.
