BBC - GCSE Bitesize: Mutualism and parasitism
Mutualism is a relationship of two organisms wherein both organisms benefit An example of mutualism is between an oxpecker and a zebra. An example of mutualism is the relationship between the Egyptian plover and Parasitism: One organism (the parasite) gains, while the other (the host) suffers. A secondary school revision resource for OCR GCSE Science about understanding our environment and competition between species.
Commensal mites travelling phoresy on a fly Pseudolynchia canariensis Commensalism describes a relationship between two living organisms where one benefits and the other is not significantly harmed or helped.
Mutualism vs. Symbiosis | Parasite Ecology
It is derived from the English word commensalused of human social interaction. It derives from a medieval Latin word meaning sharing food, formed from com- with and mensa table.

- Mutualism and parasitism
Examples of metabiosis are hermit crabs using gastropod shells to protect their bodies, and spiders building their webs on plants. Parasitism Head scolex of tapeworm Taenia solium is adapted to parasitism with hooks and suckers to attach to its host. In a parasitic relationshipthe parasite benefits while the host is harmed. Parasitism is an extremely successful mode of life; as many as half of all animals have at least one parasitic phase in their life cycles, and it is also frequent in plants and fungi.
Moreover, almost all free-living animal species are hosts to parasites, often of more than one species. Mimicry Mimicry is a form of symbiosis in which a species adopts distinct characteristics of another species to alter its relationship dynamic with the species being mimicked, to its own advantage. Batesian mimicry is an exploitative three-party interaction where one species, the mimic, has evolved to mimic another, the model, to deceive a third, the dupe.
In terms of signalling theorythe mimic and model have evolved to send a signal; the dupe has evolved to receive it from the model. This is to the advantage of the mimic but to the detriment of both the model, whose protective signals are effectively weakened, and of the dupe, which is deprived of an edible prey.
But, the relationship is harmful to the host since the parasite grows, feeds, and reproduce on the host. Sometimes, the relationship can be lethal or pathogenic to the host. Usually, the parasite is smaller than the host and shows higher reproduction rates.

Some parasites undergo several developmental stages inside their host. A Mosquito Bite The two main types of parasites are endoparasites and ectoparasites. Some of them live in the digestive system of the host and feed on the digestive food.Ecological Relationships
Some plant parasites include aphids and insects that drink the sap. Similarities Between Mutualism and Parasitism Mutualism and parasitism are two types of symbiotic relationships that can occur in an ecosystem. They occur between two species within the same habitat.
Difference Between Mutualism and Parasitism
Both types of relationships are important for the consistency of organisms. Difference Between Mutualism and Parasitism Definition Mutualism refers to interactions between organisms of two different species, in which each organism benefits from the interaction in some way. This is the basis of the difference between mutualism and parasitism.
