Food Production
Bayani Gaba-gaba
Almost everything you eat depends on farming techniques that push biological processes to their limits. From glasshouses that trap warmth and carbon dioxide to microorganisms that transform flour into bread and milk into yoghurt, food production sits at the intersection of ecology, biochemistry and engineering.
In this lesson you will explore how farmers manipulate growing conditions to maximise crop yield, weigh the trade-offs between chemical pesticides and biological control, and discover how yeast and bacteria are harnessed in industrial fermenters to produce everyday foods at scale.
Manufura
- Describe how glasshouses and polythene tunnels can be used to increase the yield of certain crops
- Understand the effects on crop yield of increased carbon dioxide and increased temperature in glasshouses
- Understand how the use of fertiliser can increase crop yield
- Understand the reasons for pest control and the advantages and disadvantages of using pesticides and biological control with crop plants
- Understand the role of yeast in the production of food including bread
- Investigate the role of anaerobic respiration by yeast in different conditions
- Understand the role of bacteria (Lactobacillus) in the production of yoghurt
- Understand the use of an industrial fermenter and explain the need to provide suitable conditions
