What this dot point is asking
CCEA wants you to explain how consumer food choices and demand influence farm production, distinguish intensive from extensive farming (including organic methods), and describe how products are processed, preserved and transported from the farm to the supermarket shelf.
Consumer choices and demand
Consumer demand then shapes farm production: if consumers want more organic, free-range or local food, farmers respond by producing it. So the market, not just the farm, decides what is grown and how.
Intensive and extensive farming
- Intensive advantages: high output from limited land, lower cost per unit, steady supply to meet demand.
- Intensive disadvantages: animal welfare concerns, higher disease risk, more chemical use and pollution, lower biodiversity.
From farm to supermarket shelf
Food is processed to make it safe and ready to sell, and the steps differ by product.
Foods are also preserved for later use by drying, vacuum packing, tinning (canning) or curing, then transported and stored to reach the consumer in good condition.
Examples in context
Example 1. Rising demand for free-range eggs. As consumers became more concerned about hen welfare, demand for free-range eggs grew and demand for caged eggs fell. Egg producers responded by switching to free-range systems, showing how consumer choice and demand directly change farm production methods.
Example 2. Curing to preserve pork. A processor turns fresh pork into bacon by curing it (with salt and sometimes smoking). This preserves the meat so it lasts longer and can be transported and stored, and it creates a different product at a different price, illustrating both preservation and processing.
Try this
Q1. State the difference between intensive and extensive farming. [2 marks]
- Cue. Intensive: maximum output from a small area with high inputs. Extensive: a larger area with lower inputs.
Q2. Name two methods of preserving food. [2 marks]
- Cue. Any two: drying, vacuum packing, tinning (canning), curing.

CCEA Unit 2 style6 marksExplain the difference between intensive and extensive farming, and assess the advantages and disadvantages of intensive farming.Show worked answer →
Marks for the definitions and for balanced advantages and disadvantages.
Intensive farming aims to get the maximum output from a small area of land or a set number of animals, using high inputs such as fertilisers, concentrated feed, housing and labour. Extensive farming uses a larger area with lower inputs per animal or per hectare, for example animals grazing freely over hill ground.
Advantages of intensive farming: high yields and output from limited land, lower cost per unit of food, and a steady supply to meet demand, which helps feed a growing population cheaply.
Disadvantages: concerns about animal welfare when animals are closely confined, higher risk of disease spread, greater use of chemicals and possible pollution, and lower biodiversity. Organic methods are an alternative that avoid artificial chemicals.
Markers reward the high-input small-area versus low-input large-area distinction plus balanced advantages and disadvantages.
CCEA Unit 2 style4 marksDescribe how milk is processed and made ready for sale after it leaves the farm, and name one method of preserving food.Show worked answer →
Three marks for milk processing and one for a preservation method.
After milk leaves the farm it goes through processing to make it safe and saleable: it passes quality control checks, then pasteurisation (heating to kill harmful bacteria), and homogenisation (breaking up the fat so it is evenly spread and does not separate as cream). It is then packaged and transported chilled to the supermarket.
A method of preserving food is drying, vacuum packing, tinning (canning) or curing (any one).
Markers reward the key milk steps (quality control, pasteurisation, homogenisation, packaging/transport) plus one valid preservation method.
