What will happen if we keep a fish in a closed container without any aquatic plants???Give reasons for your answer.
Fish, in a closed container without any aquatic plant will die after some time. Aquatic plants, through the process of photosynthesis could supply oxygen to the fish, if these were present in that closed container along with the fish. But without any aquatic plant or an external source of oxygen, fish will not be able to survive in that closed container,
