    • Nitrogen
    • Oxygen

  4. Destruction of peat bogs for compost creates a conflict between conservation and what?

    • Biofuel production

    • Food production
    • Waste management

  5. What term describes the variety of species lost when peat bogs are destroyed?

    • Biodiversity
    • Biomass
    • Biofuel
    • Biotechnology

  6. Which global issue is directly worsened by destroying and burning peat bogs?

    • Acid rain
    • Ozone depletion
    • Global warming
    • Eutrophication

  7. What term describes the variety of species in habitats such as bogs?

    • Abiotic factors
    • Photosynthesis
    • Biodiversity
    • Food security

  8. What product is peat most commonly extracted from bogs to produce?

    • Garden compost
    • Biofuel pellets
    • Animal bedding
    • Building insulation

  9. A 40-hectare bog is cleared and the species living there decline. Which concept is affected?

    • Biodiversity
    • Abiotic factors
    • Food security
    • Photosynthesis

  10. What is the main environmental impact of clearing wild grassland for farming?

    • Global cooling

  11. Which greenhouse gas is released into the atmosphere when peat decays?

    • Carbon dioxide
    • Nitrous oxide
    • Methane
    • Sulfur dioxide

  12. Why does using peat for compost contribute to climate change?

    • Absorbs atmospheric oxygen
    • Produces toxic ash
    • Releases carbon dioxide
    • Destroys the ozone

    • No overall change

  15. Which other listed activity removes land in the same way as dumping waste?

    • Recycling
    • Quarrying
    • Biogas production
    • Composting

  16. Why do intact peat bogs help prevent global warming?

    • They store carbon
    • They release oxygen
    • They absorb methane
    • They reflect sunlight

  17. Which process releases carbon dioxide from peat when bogs are drained?

    • Photosynthesis by moss
    • Decay by microorganisms

    • 60%
    • 150%
    • 25%

  20. Why is there a conflict between cheap food production and peat conservation?

    • Water scarcity
    • Land availability
    • Energy demands
    • Crop diseases
