Aquatic plants carry out photosynthesis to obtain food. In the process, oxygen bubbles are released to the aquatic environment. The rate of photosynthesis is affected by several environmental factors such as temperature, light intensity and concentration of carbon dioxide. Tumbuhan akuatik melakukan fotosintesis untukmendapatkan makanan. Semasa proses tersebut, gelembung oksigen dibebaskan kepersekitaran akuatik.Kadar fotosintesis dipengaruhi oleh beberapa factor persekitaran seperti suhu, keamatan cahaya, dan kepekatan karbon dioksida.
