5.2 - Crop Yield



Related to the: 


rate of photosynthesis - this is the combination of CO2 and water with light (enzyme) to form glucose (starch) and oxygen 
- Increasing the concentration of CO2, CO2 is the substrate 
- Shown in graph - rate of ps will increase the yield until the greatest yield point 


Temperature - Increasing 
- Shown in graph - rate of ps increases as temperature increase up to an optimum (peak)  temperature 


Increasing temperature in a greenhouse can also avoid frost damage and provide constant temperature - both contribute to increase in yield 


Both have limits (optimums)
