The 20 questions

  1. How can livestock farmers reduce energy transfer from animals to the environment?

    • Reduce protein
    • Lower temperature
    • Increase movement
    • Limit movement

  2. Why are livestock in intensive farming sometimes fed high-protein food?

    • To control temperature
    • To limit movement
    • To increase growth
    • To reduce respiration

  3. What main type of objection do some people have towards modern intensive farming?

    • Biological objections
    • Chemical objections
    • Physical objections
    • Ethical objections

  4. What is the main goal of restricting energy transfer from food animals?

    • Increase respiration rate
    • Reduce growth rate
    • Improve production efficiency
    • Enhance local biodiversity

  5. How can livestock farmers improve the efficiency of food production?

    • Increasing energy transfer
    • Lowering animal protein
    • Promoting animal movement
    • Restricting energy transfer

  6. Why is temperature controlled in intensive livestock farming sheds?

    • Increase heat loss
    • Reduce protein needs
    • Increase respiration rate
    • Reduce heat loss

  7. Why does restricting animal movement increase the energy available for growth?

    • Saves movement energy
    • Increases respiration rate
    • Increases heat loss
    • Reduces protein uptake

  8. What energy cost is reduced by keeping livestock in warm surroundings?

    • Excretory waste
    • Enzyme production
    • Movement energy
    • Body heat energy

  9. Which two factors are controlled in intensive farming to reduce energy loss?

    • Mating and humidity
    • Water and space
    • Light and oxygen
    • Movement and temperature

  10. Why are livestock fed high-protein foods in intensive farming?

    • Lower respiration rate
    • Restrict energy loss
    • Increase growth rate
    • Reduce heat loss

  11. What main issue do many people have with intensive farming methods?

    • Reduced meat growth
    • Lower crop yields
    • Ethical objections
    • High food prices

  12. What is an advantage of controlling livestock temperature and movement?

    • Increased heat loss
    • Improved animal welfare
    • Reduced growth rate
    • Efficient food production

  13. Which factor is a major disadvantage of intensive livestock farming?

    • High energy loss
    • Reduced protein levels
    • Slow growth rates
    • Ethical objections

  14. Where is saved energy transferred if an animal moves less?

    • Excreted waste
    • Sweat production
    • Thermal radiation
    • Biomass growth

  15. What is the common goal of restricting movement and controlling temperature?

    • Increase respiration rate
    • Reduce protein intake
    • Encourage natural behaviour
    • Restrict energy transfer

  16. Which method directly reduces energy spent on muscle contraction in livestock?

    • Temperature control
    • High-protein diet
    • Restricting movement
    • Artificial lighting

  17. When evaluating intensive farming, what must be balanced against output efficiency?

    • Transport distance
    • Carbon footprint
    • Ethical concerns
    • Fertiliser costs

  18. Why do public opinions differ on the use of intensive farming?

    • Cost versus colour
    • Temperature versus light
    • Growth versus age
    • Ethics versus efficiency

  19. What happens to the rate of biomass growth when animal movement increases?

    • It doubles
    • It decreases
    • It increases
    • It stays constant

  20. Pigs fed 100 kg of feed gain 25 kg. What is the efficiency of conversion?

    • 4%
    • 25%
    • 40%
    • 75%
