What this dot point is asking
AQA wants you to understand food provenance - where food comes from - and the main ways food is grown, reared and caught, with the advantages and disadvantages of each method.
What food provenance means
Growing, rearing and catching
- Arable farming grows crops such as wheat, vegetables and fruit.
- Livestock farming rears animals for meat, eggs and dairy.
- Fishing catches fish from the wild or rears them in fish farms (aquaculture).
Intensive, organic and free-range systems
Sustainable fishing
Overfishing has reduced fish stocks, so fishing is managed by quotas (limits on the catch), larger net mesh sizes (so young fish escape and breed), protected breeding areas and seasonal restrictions. This keeps stocks at a level that can replace themselves.
Sustainable fishing matters because fish stocks are a renewable resource only if they are not caught faster than they can breed. Overfishing crashed stocks such as North Sea cod in the past, harming both the marine ecosystem and the fishing industry. Aquaculture (fish farming) can take pressure off wild stocks but brings its own issues, such as disease, pollution from waste and feed, and the welfare of farmed fish.
Genetic modification
GM differs from selective breeding, the traditional method of choosing parent plants or animals with desired traits over many generations: GM directly inserts a gene in a laboratory and is much faster and more targeted. Supporters argue GM crops can help feed a growing population and reduce pesticide use; critics worry about unknown long-term effects, cross-contamination of wild species, and control of seed by large companies. Examiners reward a balanced view that recognises both benefits and concerns.

Q1. Give one advantage of organic farming. [1 mark]
- Cue. Better animal welfare, fewer artificial chemicals or less environmental harm.
Q2. Explain one way fishing can be made more sustainable. [2 marks]
- Cue. Quotas to limit the catch, or larger net mesh sizes so young fish escape and breed.
Exam-style practice questions
Practice questions written in the style of AQA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AQA 20196 marksCompare intensive farming with organic farming, giving an advantage and a disadvantage of each. (Paper 1, Section B)Show worked answer →
Intensive farming aims to produce as much food as possible from the land or animals, using chemicals (fertilisers, pesticides) and high stocking densities. An advantage is high yields and cheaper food; a disadvantage is concerns over animal welfare and environmental harm from chemicals.
Organic farming avoids artificial chemicals and uses natural methods, with higher welfare standards. An advantage is better animal welfare and less environmental harm; a disadvantage is lower yields and higher prices.
Top-band answers (5 to 6 marks) genuinely compare the two systems with a valid advantage and disadvantage for each, rather than describing them in isolation.
AQA 20224 marksExplain two ways in which fishing can be made more sustainable. (Paper 1, Section A)Show worked answer →
For 4 marks, give two methods with the reason each helps.
Quotas limit the total amount of a species that can be caught, so stocks are not overfished and can recover. Larger net mesh sizes let young, immature fish escape so they survive to breed, maintaining the population. Other valid points include protected breeding areas, closed seasons, and line-caught or pole-and-line methods that reduce bycatch.
Markers reward two distinct methods each clearly linked to keeping fish stocks at a level that can replace themselves.
