You Feed Me, I Feed You: Symbiosis - Dive & Discover
One example is the relationship between sea However, in common with many mutualisms, there is more than. Mighty Mutualisms: The Nature of Plant-pollinator Interactions . Both of the plant species have a mutualistic relationship with the pollinator, but the relative. When both members of the association benefit, the symbiotic relationship is called mutualistic. Fungi form mutualistic associations with many types of organisms.
Some biologists use it that way, too, but technically the word refers to a variety of close relationships, not just those in which both partners benefit. In some symbiotic relationships, one of the organisms benefits but the other is harmed.
An example of this is a tapeworm in a human. The tapeworm gains nourishment, while the human loses nutrients.
Mutualism (biology) - Wikipedia
In other symbiotic relationships, one of the organisms benefits and the other is neither helped nor harmed. An example of this would be an orchid growing on a tree. Symbiosis can occur between any two kinds of organisms, such as two species of animals, an animal and microbes, a plant and a fungus, or a single-celled organism such as a protist and bacteria.
In other cases, it is very difficult. The algae live inside the coral polyp and perform photosynthesis, converting energy from the sun and carbon dioxide into organic matter and chemical energy.
In the process, they give off oxygen and other nutrients that the coral needs to live. The coral polyp provides its zooxanthellae with carbon dioxide, shelter, and some nutrients.
Mutualistic relationships also occur in the deep ocean, between microbes and a wide range of animals including corals, tubeworms, and mussels. Many of these are found at cold seeps or at hydrothermal vents. Sunlight cannot penetrate into the deep ocean, so the organisms that live there cannot do photosynthesis. They must rely on a different source of energy. At cold seeps and hydrothermal vents, there are many chemicals that microbes can use to create food and energy.
Hydrogen sulfide the stuff that smells like rotten eggs and methane are two of the most common of these.
Where hydrogen sulfide is present in the seafloor around cold seeps, tubeworms are often found growing in clusters of thousands of individuals. These unusual animals do not have a mouth, stomach, or gut. Instead, they have a large organ called a trophosome that contains billions of chemosynthetic bacteria. In some cases, the trophosome accounts for more than half the weight of the tubeworm. The bacteria then use these materials plus carbon dioxide they take from the water to produce organic molecules.
A similar symbiotic relationship is found in clams and mussels that have chemosynthetic bacteria living in association with their gills. 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. In addition, another service-resource component is present, as the ants regularly feed on lipid -rich food-bodies called Beltian bodies that are on the Acacia plant.
Plants in the vicinity that belong to other species are killed with formic acid.
This selective gardening can be so aggressive that small areas of the rainforest are dominated by Duroia hirsute. These peculiar patches are known by local people as " devil's gardens ".
