ELI5: Do slow-growing plants, such as cacti, produce less oxygen and clean up CO2 slower than a fast-growing plant, such as grass?

Yes, all plants with a slower metabolic rate will consume less carbon-dioxide and will produce less oxygen. It should also be noted that roughly 80% of atmospheric oxygen is made from ocean algae and plankton, not land plants as is often assumed.
