parasitic symbiotic relationship involving protists and bacteria

A parasitic relationship is one in which one organism, the parasite, lives off of another A few examples of parasites are tapeworms, fleas, and barnacles. Some scientists say that one-celled bacteria and viruses that live in animals and Some hosts also build a symbiotic relationship with another organism that helps to. Examines symbiotic relationships between prokaryotes and other Lichens might involve a form of parasitism of the algal or bacterial cells. Commensalism is a type of relationship where one of the organisms benefits Humans have a mutualistic relationship with microorganisms, primarily bacteria, .

They get food by eating the host's partly digested food, depriving the host of nutrients. Fleas harm their hosts, such as dogs, by biting their skin, sucking their blood, and causing them to itch. The fleas, in turn, get food and a warm home. Barnacles, which live on the bodies of whales, do not seriously harm their hosts, but they do itch and are annoying. Usually, although parasites harm their hosts, it is in the parasite's best interest not to kill the host, because it relies on the host's body and body functions, such as digestion or blood circulation, to live.

Some parasitic animals attack plants. Aphids are insects that eat the sap from the plants on which they live. Parasitic plants and fungi can attack animals.

A fungus causes lumpy jaw, a disease that injures the jaws of cattle and hogs. There are also parasitic plants and fungi that attack other plants and fungi.

Ecological strategies of protists and their symbiotic relationships with prokaryotic microbes.

A parasitic fungus causes wheat rust and the downy mildew fungus attacks fruit and vegetables. Some scientists say that one-celled bacteria and viruses that live in animals and harm them, such as those that cause the common cold, are parasites as well. 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.

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.

Parasites-Symbiotic Relationships

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.

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.
