    • Fishing quotas

  2. What problem in monoculture farming do field margins and hedgerows help to reduce?

    • Water pollution
    • Soil salinisation
    • Global warming
    • Habitat loss

  3. Which rare habitat is protected and regenerated to maintain biodiversity?

    • City parks
    • Coral reefs
    • Pine plantations
    • Wheat fields

  4. Which government action helps maintain biodiversity by reducing carbon dioxide emissions?

    • Protecting tropical rainforests
    • Draining peat bogs
    • Expanding landfill sites
    • Burning fossil fuels

  5. Which feature is reintroduced in some farming areas to support wildlife?

    • Hedgerows
    • Mangroves
    • Coral reefs
    • Peat bogs

  6. Which human activity in agricultural areas leads to a reduction in biodiversity?

    • Recycling household waste
    • Creating nature reserves
    • Removing field hedgerows
    • Replanting native trees

  7. Why do scientists establish conservation programmes in ecosystems?

    • Encourage landfill expansion
    • Reduce human impacts
    • Increase land clearance
    • Promote monoculture farming

  8. Deforestation and habitat destruction are examples of which type of human interaction?

    • Positive interaction
    • Mutualistic interaction
    • Negative interaction
    • Sustainable interaction

  9. Which programme improves biodiversity on farms where only one crop is grown?

    • Increasing monocultures
    • Expanding landfill sites
    • Clearing native woodland
    • Reintroducing field margins

  10. What is the primary goal of captive breeding programmes for endangered species?

    • Expand urban development
    • Increase crop yields
    • Reduce carbon emissions
    • Prevent species extinction

  11. Which programme helps maintain biodiversity by reducing waste sent to landfill sites?

    • Recycling resources
    • Deforestation
    • Peat extraction
    • Monoculture farming

  12. Which government measure directly reduces deforestation and preserves wild habitats?

    • Expanding landfills
    • Promoting monocultures
    • Mining peat bogs
    • Protecting rainforests

  13. Which measure directly restores wildlife habitats in agricultural landscapes?

    • Burning crop stubble
    • Applying chemical fertilisers
    • Reintroducing hedgerows
    • Expanding monocultures

  14. What conflict arises when land is used for tree planting rather than agriculture?

    • Reduced food production
    • Increased landfill waste
    • Higher pesticide runoff
    • Reduced oxygen levels

  15. Which human activity represents a positive interaction with an ecosystem?

    • Practising monoculture farming
    • Regenerating rare habitats
    • Dumping landfill waste
    • Clearing tropical rainforests

  16. What is a main evaluation concern regarding breeding programmes for endangered species?

    • High financial cost
    • Increased genetic diversity
    • Automatic wild survival
    • Reduced habitat destruction

  17. How does recycling materials help to maintain ecosystem biodiversity?

    • Promotes monoculture farming
    • Destroys forest habitats
    • Reduces landfill expansion
    • Increases carbon emissions

  18. How can farmers maintain crop output while simultaneously supporting biodiversity?

    • Grow single crops
    • Reintroduce field margins
    • Remove all hedgerows
    • Drain surrounding wetlands

  19. What can still reduce biodiversity inside a protected nature reserve?

    • Captive breeding
    • Habitat regeneration
    • Field margins
    • Neighbouring pollution

  20. Why does reducing carbon dioxide emissions alone NOT fully restore biodiversity?

    • Multiple environmental factors
    • Decreased plant growth
    • Slower seed germination
    • Carbon dioxide toxicity
