Opposite of symbiotic relationship

Symbiosis - Wikipedia

opposite of symbiotic relationship

a relationship between two organisms or people or things that they continue despite its being mutually harmful -- not a one-sided relationship like parasitism or a. Some have lifelong relationships with other organisms, called symbiotic relationships. There are three different types of symbiotic relationships: mutualism. If your cat or dog has ever had fleas, you've witnessed symbiosis in action. In this lesson, learn the many types of symbiosis in biology, and how.

It derives from a medieval Latin word meaning sharing food, formed from com- with and mensa table.

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.

How Symbiosis Works

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. For example, a wasp is a strongly-defended model, which signals with its conspicuous black and yellow coloration that it is an unprofitable prey to predators such as birds which hunt by sight; many hoverflies are Batesian mimics of wasps, and any bird that avoids these hoverflies is a dupe.

Amensalism is an asymmetric interaction where one species is harmed or killed by the other, and one is unaffected by the other.

This is known as facultative symbiosis. Symbiotic relationships aren't always symmetrical -- they can be obligate for one organism and facultative for the other. The "close physical contact" part of the definition is worth looking at more closely.

In most cases, it's fairly straightforward -- one organism may make its home directly on another organism's body, or even live inside it. But biologists also consider the biochemical relationship between two organisms. If they're generating and sharing enzymes, proteins, gases or other chemicals then they can also said to be symbiotes.

Antonyms for symbiotic

Endosymbiotes live inside another organism. And by inside, biologists really mean inside -- in between cells or within the body tissues like the acoel flatworm. Ectosymbiotes live on the body of another organism. Note that organisms that live within another's digestive tract are considered ectosymbiotes. Apparently living in someone's else's intestines doesn't qualify as a close enough relationship for biologists to call them endosymbiotes.
