An experiment imposes treatment on the subjects, but an observational study does not
Explanation:
Observational studies are research studies in which an effect, process behaviour etc. are observed, without any change. For example, observation of the possible effect of a treatment on subjects.

While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
