5.2: Understand the Effects on Crop Yield of Increased Carbon Dioxide and Increased Temperature in Glasshouses

EFFECTS OF CARBON DIOXIDE AND TEMPERATURE ON CROP YIELD:

CARBON DIOXIDE	TEMPERATURE
Graph showing the Effect of Carbon Dioxide on Rate of Photosynthesis	Graph showing the Effect of Temperature on Rate of Photosynthesis
EXPLANATION: Glasshouses are Enclosed so Allows Carbon Dioxide Levels to be Controlled Farmers will Burn Paraffin Lamps to Increase Carbon Dioxide Levels in Glasshouses When Carbon Dioxide Levels Increases, it is No Longer the Limiting Factor so Rate of Photosynthesis will Increase As Rate of Photosynthesis Increases, there is More Energy for Growth, Increasing Crop Yield of Plants	EXPLANATION Glasshouses are Enclosed so Traps the Heat from the Sun, creating a Warm Climate Increased Temperature will be Closer to Optimum Temperature of Enzymes in Plants, Increasing Enzyme Activity Increased Enzyme Activity will Allow Rate of Photosynthesis to Increase As Rate of Photosynthesis Increases, there is More Energy for Growth, Increasing Crop Yield of Plants
