Rosa fills five small aquariums with equal amounts of pond water. She places various combinations of fish, plants, and/or snails in each aquarium except A, which contains only pond water. Rosa seals all the aquariums and stores them at room temperature under an aquarium light. The light provides the energy for photosynthesis in green plants and production of food and oxygen.In which aquarium would the animals live for the longest period?
