The tapeworm steals nutrients from the food in its host's intestine; without a host, the tapeworm is unable to live. The host is harmed by the tapeworm because much of its food that it eats is used by the worm. The tapeworm rarely causes its host to die, but the host suffers from weight loss and decreased energy, as well as many other health problems. Mutualism, on the other hand, is a relationship in which both organisms benefit. A classic example of a mutualistic relationship is the combination of algae and fungi, called lichens.
Lichens are often mistaken for a type of moss. The algae part of the lichen use the fungi as a place to live. The fungi protect the algae from the environment and keeps it from drying out. The fungi benefits by being able to use the sugar the algae makes through photosynthesis.
The algae can't live without the fungi, and the fungi can't live without the algae. A more familiar example of mutualism is the relationship between fruiting plants and animals that eat fruits. All plants work to make sure that their seeds get dispersed so that the parent plant isn't competing with its offspring for sunlight and water.
Fruiting plants have solved this problem by covering their seed with a tasty fruit. Animals come along, eat the fruit, and walk away.
Most of the seeds inside the fruit pass through the animals digestive tract unharmed some distance from the parent plant. The animal benefits by getting to eat the tasty and nutritious fruits and the plants benefit by getting its seeds dispersed.

Of course many of the seeds won't survive and the plant had to produce fruit in the process, but no one ever said that both organisms had to benefit equally. Commensalism is a symbiotic relationship where one organism benefits and the other is neither hurt nor harmed.
A good example many of us are probably familiar with deals with plants, like burdock, that disperse their seeds by making them sticky. Become a Contributor Examples of Commensalism for a Better Understanding of the Concept Commensalism being a type of symbiotic relationship between organisms, other types of symbiotic relationships include mutualism, in which both the organisms involved benefit from each other, and parasitism, where one of the organisms is benefited, while the other is harmed.
ScienceStruck Staff Last Updated: Mar 22, Many instances of commensalism are surrounded by controversies, as there is always a possibility that the commensal host is also being benefited or harmed in some or the other 'not-yet-known' ways.
However, here are some of the widely accepted examples of commensalism found in nature. Examples of Commensalism Cattle Egrets and Livestock One of the popular examples of commensalism is the relationship between cattle egrets and livestock.
The cattle egret is a common species of heron that is found in most regions of the world, and is mostly seen moving along with herds of cattle. This bird moves about in the pastures, and follows livestock such as cattle and horses. The cattle egret eats up the insects hiding under vegetation close to the grounds, which get stirred up when the cattle walk through them.
Orchids Growing on Branches of Trees Orchids belong to a family of flowering plants that form a commensal relationship with the trees.

It is a well-known epiphytic plant that grows on the branches or trunks of other trees. Orchids are usually found in dense tropical forests. They form their base of attachment on the branches of trees, and benefit by getting adequate sunlight and nutrition that flows down the branches.
The orchids do not grow to a large size, and thus the host tree is not harmed in any way. Remora Fish and Sharks The remora, also called suckerfish, belongs to a family of ray-finned fish. It is a small fish growing up to a size of 1 to 3 feet.
The remora forms a special relationship with sharks and other sea organisms like whales and turtles. It has special suckers attached to its fins. It attaches itself to the bodies of sharks, and uses the shark for transportation as well as protection from its predators.
It also eats up the scraps of food that are left over when the shark eats its prey. Pseudoscorpions and Beetles Pseudoscorpions are scorpion-like insects that usually grow to less than one centimeter in length. They are different from other types of scorpions in the way that they do not have stingers.

Some species of the pseudoscorpions hide themselves under the wing covers of large insects like beetles. This gives them protection from their predators, and also provides them a means of transportation over a larger area. Because of its small size and lack of sting, it does not harm the beetle in any way.
Monarch Butterfly and Milkweed The Monarch butterfly is a well-known type of butterfly found commonly in the North American region. At the larval stage, it forms a commensal relationship with certain species of milkweeds.
The milkweeds contain a poisonous chemical known as cardiac glycoside, which is harmful to almost all vertebrates. The Monarch stores these poisonous chemicals in its body throughout its lifespan.
