6 Types of Symbiotic Relationships EXPLAINED (with examples)” is Competitive Exclusion Principle: Two different species cannot share the. Symbiosis. Symbiosis means living together. Symbiotic relationships are close or intimate relationships between members of two different species. Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, . Commensalism describes a relationship between two living organisms where one benefits.

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.

Ticks are examples of parasitic symbiosis, because as blood-sucking insects that thrive on the blood of its victims, they can also harm the host by transferring an infectious disease to it taken in from the blood of another organism.

SYMBIOSIS - RELATIONSHIP BETWEEN ORGANISMS

A Symbiotic Relationship Where the Host Dies Science fiction is replete with examples of parasitoidism, but so is everyday life. In this type of symbiotic relationship, the host usually dies. Many science fiction movies feature this type of relationship between humans and aliens, like in the "Alien" movie series.

In parasitoidism, the host serves as a home for the larvae of the parasite. As the larvae mature, they escape the body of the host, killing it in the process. In nature, braconid wasps lay their eggs atop the body of a tomato hornworm, and as the wasp larvae grow, they feed off the body of the hornworm, killing it during metamorphosis. A Type of Symbiotic Relationship A well-known symbiotic relationship exists between a predator and its prey. In an ecological community, some entities live by eating the bodies of other organisms.

Thought not considered a parasitic relationship because the predator does not live in or on the body of the animal it eats, it is still a symbiotic relationship because the predator would not survive without the other organism giving up its life.

The predator usually sits above its prey in the food chain, like the lion and the gazelle, the coyote and the rabbit or a household petand the wolf and the bison or other cloven hoof animals — ungulates — like deer and antelope. Predation is also responsible for all kinds of evolution in the prey: Where One or Both Inhibit the Population of the Other Competition between species occurs when both entities vie for the same resources in the ecosystem.

Symbiotic Relationship: Definition & Examples

It is different from regular interactions between species, because in a symbiotic relationship, the two species in the relationship live together. Many organisms are involved in symbiotic relationships because this interaction provides benefits to both species. However, there are types of symbiosis that are not beneficial and may in fact harm one or both of the species. Symbiotic relationships can be obligate or facultative.

Obligate symbiosis is when two organisms are in a symbiotic relationship because they can't survive without each other. Facultative symbiosis is when the species live together by choice. There are four main types of symbiotic relationships: Mutualism Mutualism occurs when both species benefit from the interaction.

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.

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.
