Farming Techniques Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

Why is only about 10% of biomass transferred to the next trophic level?

Biomass is lost due to respiration, parts of the animal not being eaten, and excretion as faeces.

What is the aim of organic farming?

Organic farming aims to produce high-quality food using sustainable methods that benefit the entire food system.

How do free-range conditions affect biomass in chickens?

Free-range chickens use more energy to maintain body temperature and for movement, leaving less biomass for growth and egg production.

What is intensive farming?

Intensive farming, otherwise known as factory farming, uses mechanised techniques, inorganic fertilisers, herbicides, and pesticides to achieve high yields efficiently.

How can the efficiency of biomass transfer be improved in intensive farming?

Efficiency can be improved by limiting the movement of animals and controlling their environmental temperature. This reduces energy expenditure on movement and warmth.

What are the downsides of using antibiotics and removing hedgerows in intensive farming?

Using antibiotics can increase antibiotic resistance in bacteria, and removing hedgerows reduces biodiversity and increases pollution from larger farming machinery.
