Modern Farming Methods (T)

• What should you be able to describe by the end of the video?

  How to improve the efficiency of food production in farming
• What are the advantages and disadvantages discussed in the video?

  Modern farming techniques
• What ethical concerns are raised regarding intensive farming methods?

  Some people have ethical objections to intensive farming methods
• What percentage of biomass is transferred from one trophic level to the next?

  Approximately 10%
• Why is not all material eaten by an animal digested and absorbed?

  Because some material is excreted and energy is used for movement and respiration
• What is the purpose of energy released in respiration for animals?

  To provide energy for movement and maintain body temperature
• How do modern farming methods improve the efficiency of biomass transfer?

  • Restrict animal movement
  • Control temperature
  • Provide a high-protein diet
  • Reduce energy wasted in respiration
• What is a problem associated with free-range chickens?

  They waste biomass on movement and temperature regulation, limiting growth and egg production
• What is another term for intensive farming?

  Factory farming
• How does limiting movement and controlling temperature affect indoor chickens?

  It increases efficiency, leading to faster growth and more egg production
• What are the advantages of factory farming?

  • More efficient food production
  • Less biomass wasted in respiration
  • Controlled nutrient intake
  • Easier egg harvesting
• What are the disadvantages of factory farming?

  • Increased spread of infectious diseases
  • Use of antibiotics may lead to antibiotic resistance
  • Crowded conditions can increase animal stress
• Why do some people have ethical objections to intensive farming?

  Because they believe animals should live in natural conditions and engage in normal behaviors
• How does engaging in natural behavior affect animal welfare?

  It increases animal welfare by reducing stress
