This type of symbiosis is called mutualism. An example of mutualism is the relationship between bullhorn acacia trees and certain species of. One example is the relationship between sea than one aspect to it: in the anemonefish-anemone mutualism. Some have lifelong relationships with other organisms, called symbiotic An example of mutualism is the relationship between the Egyptian plover and the.
Other examples include rhizobia bacteria that fix nitrogen for leguminous plants family Fabaceae in return for energy-containing carbohydrates. Service-resource relationships are common. Three important types are pollination, cleaning symbiosis, and zoochory. In pollinationa plant trades food resources in the form of nectar or pollen for the service of pollen dispersal.
Phagophiles feed resource on ectoparasitesthereby providing anti-pest service, as in cleaning symbiosis.

Elacatinus and Gobiosomagenera of gobiesalso feed on ectoparasites of their clients while cleaning them. This is similar to pollination in that the plant produces food resources for example, fleshy fruit, overabundance of seeds for animals that disperse the seeds service.
Another type is ant protection of aphidswhere the aphids trade sugar -rich honeydew a by-product of their mode of feeding on plant sap in return for defense against predators such as ladybugs. Service-service relationships[ edit ] Ocellaris clownfish and Ritter's sea anemones is a mutual service-service symbiosis, the fish driving off butterflyfish and the anemone's tentacles protecting the fish from predators.
Strict service-service interactions are very rare, for reasons that are far from clear. However, in common with many mutualisms, there is more than one aspect to it: A second example is that of the relationship between some ants in the genus Pseudomyrmex and trees in the genus Acaciasuch as the whistling thorn and bullhorn acacia.
The ants nest inside the plant's thorns. In exchange for shelter, the ants protect acacias from attack by herbivores which they frequently eat, introducing a resource component to this service-service relationship and competition from other plants by trimming back vegetation that would shade the acacia.
By Editors Mutualism Definition Mutualisms are defined as interactions between organisms of two different species, in which each organism benefits from the interaction in some way. These types of interaction are common and ubiquitous throughout all ecosystems, and scientists are increasingly recognizing the important role that they play in ecology.
Mutualisms may involve either the exchange of resources, such as shelter, food and other nutrients, or they may involve the exchange of services, such as protection, transportation or healthcare. Sometimes mutualisms are symbiotic relationships.

In such cases, the two species live in close proximity to each other for part or all of their lives; however, not all symbiotic relationships are mutualistic. If the mutualism is vital for the growth, survival or reproduction of an organism, it is obligate; this is the case in many symbioses. If the mutualism benefits an organism, but the organism is not so dependent on the mutualism that it cannot survive without it, this is called a facultative mutualism.
Mutualisms may also be species specific or diffuse. In specific interactions, each species only has a mutualism exclusively with the other, whereas diffuse interactions involve multiple interactions between many different species. The concept of a mutualism is in contrast to interspecific competitionwhich occurs when organisms from different species compete for a resource, resulting in reduced fitness for one of the individuals or populations involved while the other benefits.
Examples of Mutualisms Cleaning Mutualisms A mutualism in which one mutualistic partner removes parasites, as well as dead or diseased skin from another, in return receiving a steady supply of food, is called a cleaning mutualism.
The wrasse is a small fish, with striking lines of bright coloration along its body. However, they also pose a risk to fish through the transmission of disease.
- Mutualism (biology)
To rid themselves of the parasites, the fish visit the cleaning stations, and allow the wrasse to move up and down their bodies even inside their mouthssearching for and eating the ectoparasites. Although the cleaner fish put themselves into apparent danger by swimming so close to larger predators, the benefits of the cleaning service to the client outweighs the benefits of eating the cleaner, and the cleaners are almost never harmed; most cleaner fish even have a clientele of repeat customers!
The image above shows a cleaner wrasse Labroides Phthirophagus searching for parasites on the body of a White-Spotted Puffer fish Arothron hispidus. Terrestrial examples of cleaning mutualisms can be seen in several species. Capybara Hydrochoerus hydrochaerislarge rodents native to Brazil, have ticks, horseflies and other parasites removed by a range of different birds, for example, the shiny cowbird Molothrus Bonariensisthe yellow-headed caracara Milvago chimachima and the Wattled Jacana Jacana jacana.
The red-billed oxpecker bird Buphagus erythrorhynchus eats ticks from many species of large mammal such as cattle, deer and rhinoceros. As well as receiving the benefit of parasite removal, the red-billed oxpecker alerts its host to danger, by flying high in the sky and making loud noises.
Cleaning mutualisms are generally diffuse relationships, as the interactions are not entirely species specific, with many different cleaners specializing in one client, or many clients using the services from one species of cleaner.
Pollination Nearly all pollination services involve a mutualism that has evolved over millions of years.
