🌍 Part 2: Sustainability and Human Impact

5. Explain how deforestation affects the carbon cycle and contributes to climate change:

6. A native New Zealand forest has 45 different plant species. After urban development, only 12 species remain. Calculate the percentage decrease in plant biodiversity:

7. Which sustainable practices can help protect plant ecosystems? (Select all that apply)

Replanting native species

Using pesticides regularly

Creating protected reserves

Sustainable forestry practices

📊 Part 3: Data Analysis and Critical Thinking

8. A student measured the rate of photosynthesis in aquatic plants at different light intensities. The results showed: 5 lux = 2 bubbles/min, 10 lux = 8 bubbles/min, 15 lux = 12 bubbles/min, 20 lux = 12 bubbles/min. What can you conclude about the relationship between light intensity and photosynthesis rate?

9. Evaluate the effectiveness of two different conservation strategies for protecting native New Zealand plants. Consider both environmental and economic factors in your answer:

10. Design an investigation to test how different environmental factors affect plant growth. Include your hypothesis, method, and variables:
