Symbiosis - Wikipedia
Commensalism Examples. It refers to a relationship between two living things from different species in which one of the Symbiosis Reading Comprehension. It describes a close relationship between two organisms from different species. Commensalism; Parasitism; Mutualism; Eendosymbiosis and ectosymbiosis. Symbiosis is any type of a close and long-term biological interaction . Commensalism describes a relationship between two living organisms where one benefits and the other is not significantly harmed or.
The benefits for one organism can be in a variety of forms, including food, shelter, transportation and seed dispersal. Types of Commensalism Most experts in the field of ecology group commensal relationships into four main types: Chemical commensalism is most often observed between two species of bacteria.
It involves one species of bacteria feeding on the chemicals produced or the waste products that are not used by the other bacteria. Inquilinism involves one species using the body or a body cavity of another organism as a platform or a living space while the host organism neither benefits nor is harmed.
Metabiosis is a form of commensalism that occurs when one species unintentionally creates a home for another species through one of its normal life activities.
A phoresy takes place when one organism attaches to another organism specifically for the purpose of gaining transportation. Examples of Commensalism An example of inquilinism can be observed between barnacles and whales. Barnacles are normally sessile, or non-moving sea creatures.
They rely on currents to bring food past them in order to eat. 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. When a bird eats a Monarch butterfly, it finds it distasteful, and gets sick. Thus, they avoid eating it. Birds Following Army Ants Many birds form a commensal relationship with some species of ants like the army ants. A great number of army ants trail on the forest floor, and while moving, stir up many insects lying in their path. The birds follow these army ants and eat up the insects that try to escape from them.
The birds benefit by catching their prey easily, while the army ants are totally unaffected.
Commensalism: Relationship Examples, Definition & Types
Burdock Seeds on the Fur of Passing Animals Many plant species have adapted themselves by developing curved spines on their seeds or seedpods in order to disperse them over a larger area. The burdocks are a common type of weed that are mostly found along roadsides, and on barren land and fields. The burdock seeds have long, curved spines attached to them. They easily catch onto the fur of passing animals, which carry and drop off these seeds to other regions. Barnacles and Whales The barnacles are a type of crustaceans that are sedentary, i.

At their larval stage, they stick to the bodies of other organisms like whales, and other places like shells, rocks, or even ships, and grow on their surface.
While the whales are on the move, the barnacles catch hold of floating plankton and other food material using their feather-like feet. This way, they get the nutrition and transportation, and the whale is not harmed or benefited in any manner. Emperor Shrimp and Sea Cucumbers Emperor shrimp is a small crustacean that is usually found in the Indo-Pacific region.
It can be seen hitching a ride on sea cucumbers. These shrimp get protection as well as a mode of transportation to move about in larger areas in search of food, without spending any energy on their own. They get off from their host sea cucumber to feed, and get back on for a ride when they want to move to other areas.
Decorator Crabs and Sea Sponges Decorator crabs have undergone a very unique adaptation for concealing and camouflaging themselves. As the name suggests, the decorator crabs snip off material available in their surrounding environment, and decorate their shells.
In forming a commensal relationship with the sea sponges, they carve out small pieces of sponges and camouflage themselves using them.
