What are 3 conditions for photorespiration?????

Dear student,
Photorespiration is the futile process that occurs under following conditions:
1: Higher temperature: Plants close stoamta under higher temperature to prevent water loss. This causes increased oxygen concentration as it is not released in air and favors photorespiration.
2: Lower CO2 levels: Relatively lower concentration of CO2 as compared to oxygen concentration favors photorespiration.
3: Increased oxygen levels: Increased oxygen concentration favors photorespiration as RuBisCO has higher affinity for oxygen as comapared to that for CO2.
Regards.
