Symbiosis - Wikipedia
Obligate symbiosis is when two organisms are in a symbiotic relationship because they can't survive without each other. Facultative symbiosis is when the . There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: The crocodile does not eat the plover. Instead. 6 Types of Symbiotic Relationships EXPLAINED (with examples)” is published by Ernest Wolfe in cypenv.infoion.
Not Obligatory, but Beneficial to Both The clown fish and the anemone represent protocooperation symbiosis, a relationship that benefits both, but unlike the termite's and its symbionts, both can survive independently of the other.
The fish has a home within the fat, wavy arms of the anemone that protects the fish from predators; the fish also protects the anemone from its predators and sometimes even brings it food.
Cells Living in Other Cells When one organism lives inside the tissue or cells of another, biologists define that as endosymbiosis. For the most part, these relationships are the norm for many unicellular entities.
For example, a unicellular eukaryotic a cell with an encased nucleus inside it organism Paramecium bursaria serves as a host to eukaryotic Chlorella algae cells. The alga produces energy via the photosynthesis process, and the paramecium benefits as it receives some of that energy or food. Additionally, the algae reside inside a protected, mobile home — the body of the paramecium.

Organisms That Live on the Surface of Another Another kind of mutualistic symbiosis involves one organism living on the skin or surface of another in a mutually beneficial relationship. Leaf cutter ants have a special symbiont, a type of unicellular bacteria that lives on their skin. Leaf cutter ants bring the cut foliage back to the colony where they inject it with a special type of fungus.
The fungus serves as a food source for the colony, which the bacteria protect from other invading fungi species. Transport Hosts and Food Sources A phoresy symbiotic relationship occurs when one organism lives on or near the body of another, but not as a parasite, and performs a beneficial service to the host and itself.
A species of marine life, the remora fish, attach themselves to the bodies of whales, manta rays, sharks and turtles and even ships via sucking discs atop their heads.
The remora, also called shark suckers, don't harm the host nor take anything from it other than eating the parasitic sea creatures that infest it. Remora fish also use the disc to hitchhike a ride from the host. Oxpecker birds are common sites atop the backs of rhinoceros where they eat the parasites and ticks living there.
They also fly in the air and scream when danger nears, providing a warning for the rhinoceros or zebra host.
One Organism Benefits, the Other Is Unharmed Commensalistic relationships are those where one species receives all the benefit from its relationship with the other, but the other receives no benefit or harm.
A good example of this type of relationship occurs between grazing cattle and cattle egrets. As the cattle graze in the grass, they stir up the insects living there, allowing the cattle egret a tasty meal.
The cattle egrets get a meal, but the cattle receive nothing in return from the long-necked birds, nor are they harmed by the relationship.

One Benefits, the Other May or May Not Suffer The world is full of parasitic relationships where a living entity makes a home in or atop a host entity. Most of the time, the parasite feeds on the host's body but does not kill the host.
Two types of hosts exist in these relationships: A definitive host provides a home to an adult parasite, while an intermediate host unknowingly offers a home to a juvenile parasite. It is derived from the English word commensalused of human social interaction. It derives from a medieval Latin word meaning sharing food, formed from com- with and mensa table. Examples of metabiosis are hermit crabs using gastropod shells to protect their bodies, and spiders building their webs on plants.
Parasitism Head scolex of tapeworm Taenia solium is adapted to parasitism with hooks and suckers to attach to its host. In a parasitic relationshipthe parasite benefits while the host is harmed.
Parasitism is an extremely successful mode of life; as many as half of all animals have at least one parasitic phase in their life cycles, and it is also frequent in plants and fungi.
Moreover, almost all free-living animal species are hosts to parasites, often of more than one species. Mimicry Mimicry is a form of symbiosis in which a species adopts distinct characteristics of another species to alter its relationship dynamic with the species being mimicked, to its own advantage.
Because mutualism is beneficial to both species involved, there are a wide variety of mutualistic interactions, and these are most common in nature. For example, there may be a nutritional benefit to be gained from the symbiosis, such as with lichen.
Symbiotic Relationship: Definition & Examples
Lichen is made up of both algae and fungi, and together they provide each other with food and structure. This type of symbiosis is both obligate and mutualistic. Pollination symbiosis is another example of an obligate, mutualistic symbiosis.
Pollinators, such as bees and birds, receive nectar from plants while transporting pollen that the plants need for fertilization. Cleaning symbiosis is a facultative mutualistic symbiosis. In this case, one organism cleans parasites off another organism's body, which in turn provides a source of food.
