a) Food Production

 * Learning outcomes //(students will be assessed on their ability to)//**
 * || Crop plants ||
 * 5.1 || describe how glasshouses and polythene tunnels can be used to increase the yield of certain crops ||
 * 5.2 || understand the effects on crop yield of increased carbon dioxide and increased temperature in glasshouses ||
 * 5.3 || understand the use of fertiliser to increase crop yield ||
 * 5.4 || understand the reasons for pest control and the advantages and disadvantages of using pesticides and biological control with crop plants ||
 * || Micro-organisms ||
 * 5.5 || understand the role of yeast in the production of beer ||
 * 5.6 || describe a simple experiment to investigate carbon dioxide production by yeast, in different conditions ||
 * 5.7 || understand the role of bacteria (Lactobacillus) in the production of yoghurt ||
 * 5.8 || interpret and label a diagram of an industrial fermenter and explain the need to provide suitable conditions in the fermenter, including aseptic precautions, nutrients, optimum temperature and pH, oxygenation and agitation, for the growth of micro-organisms ||
 * || Fish Farming ||
 * 5.9 || explain the methods which are used to farm large numbers of fish to provide a source of protein, including maintenance of water quality, control of intraspecific and interspecific predation, control of disease, removal of waste products, quality and frequency of feeding and the use of selective breeding. ||
