Answer 2

(iii) The respiration in animals occurs at a much faster rate. (b) (i) During daytime when photosynthesis occurs, oxygen is produced. ... Carbon dioxide produced by respiration diffuses out into air. So, the net gas exchange in leaves at night is: Oxygen diffuses in; Carbon dioxide diffuses out.
