Ctenophora predation by ctenophores may control the populations of small zooplanktonic organisms such as copepods, which might otherwise wipe out the phytoplankton (planktonic plants), which are a vital part of marine food chains. Almost all ctenophores are predators – there are no vegetarians and only one genus that is partly parasitic. If food is plentiful, they can eat 10 times their own weight per day. While "Beroe" preys mainly on other ctenophores, other surface-water species prey on zooplankton (planktonic animals) ranging in size from the microscopic, including mollusc and fish larvae, to small adult crustaceans such as copepods, amphipods, and even
Dunaliella strain is reported to have oil yield of about 37% (organic basis). "D. tertiolecta" is a fast-growing strain and that means it has a high CO sequestration rate as well. Dunaliella Dunaliella is a genus of the algae family Dunaliellaceae. "Dunaliella" sp. are motile, unicellular, rod to ovoid shaped (9−11 µm) green algae (Chlorophyceae), which are common in marine waters. The organisms are relatively simple to cultivate and do not clump or form chains. The best-known species is the extremely salt tolerant "Dunaliella salina" Teodor. A new species of "Dunaliella" was discovered in the Atacama Desert in 2010. It is
