They swim across the lake to the East at night and the process starts again the next morning. [97] Some jellyfish have a symbiotic relationship with single-celled dinoflagellates, allowing them to assimilate inorganic carbon, phosphorus, and nitrogen creating competition for phytoplankton. 6 Symbiotic Relationships in Coral Reef Ecosystem . With the higher ocean levels, creatures like the golden jellyfish trickled into an island lake. There are typically about 5 million golden jellyfish in the lake. The reason I asked is that there is a very common jellyfish, Cassiopeia, which also uses symbiotic algae for energy, and as far as I know hasn't ever been trapped anywhere. Solar rays nourish essential, algae-like organisms called zooxanthellae, which live symbiotically in the jellies’ tissues and provide their hosts with energy as a byproduct of their photosynthesis. The East at night and the development of an oxygen rich atmosphere has this been established or is this assumption.
