Oxygen consumption was measured in the algal‐bearing and aposymbiotic hydra, Hydra viridis using a microrespirometer. In the light, green animals exhibited a lower rate of oxygen consumption than green animals in the dark or aposymbiotic animals. Treatment of the algal‐bearing animals with the photosynthetic inhibitor DCMU demonstrated that oxygen produced by symbiotic algae as a result of photosynthesis may supply part of the host's respiratory needs.
