Reproductive isolating mechanisms are barriers which impeded mating (prezygotic) or prevent the hybrid from developing properly (postzygotic) but the overall effect is to cause speciation by making it difficult for two diverging species to share genes. So one kind of mechanical isolation could be the usage of contraceptives. As of temporal isolation, or behavioral isolation could be exemplified by people who suffer from diseases that cause separation (such as HIV or cancer). I hope that this is the answer that you were looking for and it has helped you.

Answer:
plants process oxygen for respiration as an aerobic organism and also produces it, light can regulate this metabolism, which means that in the presence of light oxygen generation occurs as well as consumption and when there is darkness only consumption will occur Thus, when calculating the amount of oxygen that a plant produces during photosynthesis, it will be necessary to subtract the oxygen it consumes, from which it is deduced that the rate of oxygen consumption will not have variations and will be the same in the day and in the At night, so the change of oxygen in the dark is subtracted with the change of volume of oxygen in the light phase
