💬 Short Answer – Sample Answers

1. To avoid poison or danger, as many brightly colored bugs are toxic.
2. Warmth, moisture, oxygen, and the presence of decomposers like bacteria or fungi.
3. A mixture contains two or more substances physically combined, while a compound is chemically bonded.
4. Spinning (centrifugation) separates cream based on density differences.
5. Biodiversity is important because it ensures ecosystem stability, food variety, and medicine sources.

📖 Long Answer – Sample Points

1. Flow of Energy in a Food Chain:
   Starts from producers (plants) → primary consumers (herbivores) → secondary consumers (carnivores) → decomposers.
   Example: Grass → Grasshopper → Frog → Snake → Eagle.
   Energy is transferred as food, and only about 10% moves to the next level.
2. Effects of Biodiversity Loss:
   • Fewer resources for humans (food, medicine)
   • Ecosystem imbalance
   • Increased vulnerability to environmental changes
3. Traditional Fijian Practices:
   • Tabu areas: no fishing or harvesting for a period
   • Planting mangroves
   • Sustainable farming methods
     These protect species and preserve ecosystems.
4. Reversible vs. Irreversible Changes:
   • Reversible: Melting ice, boiling water
   • Irreversible: Burning wood, rusting iron
     Important in science to classify processes and understand materials’ behavior.
