1. Sustainability

2. Abiotic components (non-living things)

2.1. Air

2.2. Water

2.3. Rock

2.4. Soil

2.5. Sunlight

3. Biotic components (living things)

3.1. Five basic needs

3.1.1. Food

3.1.2. Water

3.1.3. Oxygen

3.1.4. Energy

3.1.5. Suitable habitat

3.2. Producers

3.2.1. Plants

3.2.2. Most algae, a few bacteria

3.2.3. Make their own food

3.2.3.1. Photosynthesis

3.2.3.1.1. Sunlight + Carbon dioxide + Water → Food (glucose) + Oxygen

3.3. Consumers

3.3.1. Animals

3.3.1.1. Respiration

3.3.1.1.1. Food (glucose) + Oxygen → Energy + Carbon Dioxide + Water

3.3.2. Fungi, most bacteria

3.3.3. Basic types

3.3.3.1. Herbivores

3.3.3.2. Omnivores

3.3.3.3. Carnivores

3.3.4. Special types

3.3.4.1. Scavengers

3.3.4.2. Decomposers

4. Food chains

5. Food webs

6. Energy pyramids

7. Cycling of matter

7.1. producer to consumer to decomposer and back to producer again!

7.2. Oxygen

7.3. Carbon

8. Owls

8.1. Habitat

8.2. Prey

8.2.1. Owl pellets

8.2.1.1. What they are

8.2.1.2. How they are made and why

8.3. Behaviour

8.3.1. Night hunters

8.4. Physical features
