The association could be beneficial to both mutualismbeneficial to one but harmful to the other parasitismor beneficial to one with the other unaffected by the association commensalism.
The fireflies produce light through a chemical reaction in their glowing abdomens, a process known as bioluminescence. But did you know that seascapes can also glow and glitter thanks to the light producing abilities of many marine organisms?
Some fish dangle a lighted lure in front of their mouths to attract prey, while some squid shoot out bioluminescent liquid, instead of ink, to confuse their predators. Worms and tiny crustaceans also use bioluminescence to attract mates. Humans primarily see bioluminescence triggered by a physical disturbance, such as waves or a moving boat hull, that gets the animal to show their light off, but often animals light up in response to an attack or in order to attract a mate.
Bioluminescent organisms live throughout the water column, from the surface to the seafloor, from near the coast to the open ocean. In the deep sea, bioluminescence is extremely common, and because the deep sea is so vast, bioluminescence may be the most common form of communication on the planet!
For a reaction to occur, a species must contain luciferin, a molecule that, when it reacts with oxygen, produces light.
There are different types of luciferin, which vary depending on the animal hosting the reaction. Many organisms also produce the catalyst luciferase, which helps to speed up the reaction.
Animals can closely control when they light up by regulating their chemistry and brain processes depending on their immediate needs, whether a meal or a mate. They can even choose the intensity and color of the lights.
A biological clock triggers bioluminescence in the dinoflagellate Pyrocystis fusiformis. At dusk, cells produce the chemicals responsible for its light. In fish alone, there are about 1, known species that luminesce. In some cases, animals take in bacteria or other bioluminescent creatures to gain the ability to light up.
For example, the Hawaiian bobtail squid has a special light organ that is colonized by bioluminescent bacteria within hours of its birth. But usually, the animal itself contains the chemicals necessary for the reaction that produces bioluminescence. The number of species that bioluminesce and the variations in the chemical reactions that produce light are evidence that bioluminescence has evolved many times over—at least 40 separate times!
This number continues to grow as research makes new discoveries. That's quite an increase from the handful of times that were known before.
Many small planktonic surface dwellers—such as single-celled dinoflagellates—are bioluminescent. When conditions are right, dinoflagellates bloom in dense layers at the surface of the water, causing the ocean to take on a reddish-brown color in daylight and a sparkly sheen as they move in the waves at night.
When the dinoflagellates are poisonous to other animals, these events are called harmful algal blooms HABs. When they're eaten, the toxic dinoflagellates accumulate in high concentrations in larger fish and filter feeding shellfish.Bacteria carry out the process of chemosynthesis by extracting inorganic compounds from their environment and converting them into organic nutrient compounds without the prese nce of sunlight.
Hydrothermal vent dwellers carry chemosynthetic bacteria usually located in their tissue or in their gills. These bacteria are known as Chemosynthesis Autotrophs.
This partnership between bacteria and animals is called symbiosis.
Parasitism and mutualism Parasitism. Parasites are organisms that live on or in a host organism. The parasite benefits from this arrangement, but the host suffers as a result. Organisms near an ocean vent do not always have access to sunlight. These organisms depend on a process called chemosynthesis. In chemosynthesis, microbes convert vent fluids such as hydrogen sulfide into energy (simple sugars), water, and sulfur. Search» All» Science» Biology» Biology Chapter 3 Don't know.

Energy and Matter in Ecosystems This lioness will gain energy from this Some bacteria, called cyanobacteria, carry out photosynthesis. Cyanobacteria, like those in Table 1, have chemosynthetic bacteria live deep in the ocean, where the Sun’s rays never reach.
Larger animals then eat the chemo-. What Uses Chemosynthesis? There is a Bacteria that is capable of doing this.
It live inside other animals like the red tube-worm. What’s Chemosynthesis? Chemosynthesis is a way of turning carbon into energy, for an organism. Why Does it Matter? There is no light deep in the ocean, so autotrophs must make food another way, so they use.
Nov 01, · Unlike most other organisms that carry out photosynthesis in specialized organelles, these bacteria make the conversion directly in the cytoplasm of their cells. Evolutionary History Many evolutionary biologists say that the chloroplasts found in most living plants are probably descended from or were once created by cyanobacteria.
