understand the effects on crop yield of increased carbon dioxide and increased temperature in glasshouses
Increased concentration of CO2:
- Substrate
- Rate of photosynthesis increases which means that there is a higher yield
Increased temperature:
- Increase in rate of photosynthesis which means that there is a higher yield
- There is an optimum temperature along the graph
- Avoiding frost damage, Constant temperature --> higher yield
Both of the conditions have limits
