You scratch my back the beneficial (and not so beneficial) relationships between organisms
Parasites get their food from other living organisms, harming, but not killing them. Then there are the different kinds of symbiotic relationship which involve and bacteria, various worms, plants, fungi, insects, and even birds and mammals. The cuckoo (Cuculus canorus) is well-known for its habit of laying its eggs in the . In this relationship, all of the benefits go to the parasite; the host is harmed by the relationship. An example is a human and a tapeworm living in. Predation, parasitism, competition all living beings, besides What types of relationships in addition to those you know? but there are also vertebrate parasites, like the cuckoo that lay their eggs in Parasites that live inside the host's body are called endoparasites (such as tapeworms), and those who.Swallowing Tape Worm Eggs! - Earth Lab
Many insects such as mosquitoes, of course, act as vectors of parasites. Parasites are also identified as either endoparasites or ectoparasites depending on whether they are located internally or externally with respect to the host. Parasites often have incredibly complicated life cycles and employment of control measures against parasites requires detailed knowledge of these life cycles.

Associations between different species of animals can take various forms ranging from commensalism, through mutualism to parasitism. In commensalism both partners live independently, in mutualism there is an obligatory intimate relationship between the partners which is beneficial to both and, in parasitic relationship one partner benefits at the expense of the other. Most parasitic species are invertebrates but there are some vertebrate parasites such as the cuckoo.

There are important medical and veterinary parasites in all the major groups of protozoan and metazoan animals. Parasites can be found inside their host and are known as endoparasites whereas some found outside their hosts and are known as ectoparasites. Devising strategies to control parasites and avoid infection depends on an understanding of the life cycle of the parasites. Some examples of parasitic protozoa. Trichonympha is found in wood eating termites and digests cellulose in the termites wood diet; Trichomonas vaginalis is found in the human vagina and is transmitted by sexual intercourse; Giardia is found in the small intestine and causes diarrhoea; Trypanosoma brucei is the tsetse fly transmitted agent of sleeping sickness in humans and the disease is fatal unless treated; E.
This plant grows on a wide range of host trees and commonly stunts their growth, but can kill them with heavy infestation. Mistletoe is not completely dependent on its host and has its own leaves that do some photosynthesis.
It uses the host mainly for water and mineral nutrients. Well-adapted parasites have typically evolved not to kill their hosts. What about mosquitoes, which drink human blood?
Parasites usually live in a very intimate relationship with their host, depending on it for more than nutritional requirements. The host is a source of food and at the same time provides a more-or-less permanent habitat. So, a mosquito is more properly a tiny predator. But mosquitoes also transmit disease-causing micro-organisms such as the malaria protozoan or dengue virus.
These are true parasites. Mutualism Mutualism is a relationship in which both partners benefit from the interaction. The classic example of mutualism is lichen, a long-term association between a fungus and a green alga or blue-green cyanobacterium. Parasitic Relationships A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death.
The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. 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.
