Answer 2

Answer:

It is because on a hot sunny day stomata closes to prevent the loss of water and level of oxygen rises because closed stomata do not let it go.

              So, photorespiration(the respiratory activity occur in plants during day time) occurs and ribulose bisphosphate(RuBP) begin to bind with oxygen in presence of rubisco. and photorespiration occur which uses oxygen nd releses CO₂.It isthe reverse of Clavin Benson cycle.
