Mutualism (biology) - Wikipedia
For example, people enjoy a symbiotic relationship with the flora that reside in the Mutualistic relationships defined under symbiosis are those Some ant species are even known to take aphid eggs into the nest's storage. Some have lifelong relationships with other organisms, called symbiotic relationships. There are three different types of symbiotic relationships: mutualism. Symbiosis is a relationship between two organisms: it can be mutualistic (both .. of the association benefit, the symbiotic relationship is called mutualistic.
Transport Hosts and Food Sources A phoresy symbiotic relationship occurs when one organism lives on or near the body of another, but not as a parasite, and performs a beneficial service to the host and itself.

A species of marine life, the remora fish, attach themselves to the bodies of whales, manta rays, sharks and turtles and even ships via sucking discs atop their heads. The remora, also called shark suckers, don't harm the host nor take anything from it other than eating the parasitic sea creatures that infest it.
Remora fish also use the disc to hitchhike a ride from the host. Oxpecker birds are common sites atop the backs of rhinoceros where they eat the parasites and ticks living there.
They also fly in the air and scream when danger nears, providing a warning for the rhinoceros or zebra host. One Organism Benefits, the Other Is Unharmed Commensalistic relationships are those where one species receives all the benefit from its relationship with the other, but the other receives no benefit or harm. A good example of this type of relationship occurs between grazing cattle and cattle egrets.
As the cattle graze in the grass, they stir up the insects living there, allowing the cattle egret a tasty meal.
The cattle egrets get a meal, but the cattle receive nothing in return from the long-necked birds, nor are they harmed by the relationship.
One Benefits, the Other May or May Not Suffer The world is full of parasitic relationships where a living entity makes a home in or atop a host entity. Most of the time, the parasite feeds on the host's body but does not kill the host.
Symbiosis - Wikipedia
Two types of hosts exist in these relationships: A definitive host provides a home to an adult parasite, while an intermediate host unknowingly offers a home to a juvenile parasite. Ticks are examples of parasitic symbiosis, because as blood-sucking insects that thrive on the blood of its victims, they can also harm the host by transferring an infectious disease to it taken in from the blood of another organism.
A Symbiotic Relationship Where the Host Dies Science fiction is replete with examples of parasitoidism, but so is everyday life.
In this type of symbiotic relationship, the host usually dies. Many science fiction movies feature this type of relationship between humans and aliens, like in the "Alien" movie series. In parasitoidism, the host serves as a home for the larvae of the parasite. As the larvae mature, they escape the body of the host, killing it in the process. In nature, braconid wasps lay their eggs atop the body of a tomato hornworm, and as the wasp larvae grow, they feed off the body of the hornworm, killing it during metamorphosis.
A Type of Symbiotic Relationship A well-known symbiotic relationship exists between a predator and its prey. In an ecological community, some entities live by eating the bodies of other organisms. Thought not considered a parasitic relationship because the predator does not live in or on the body of the animal it eats, it is still a symbiotic relationship because the predator would not survive without the other organism giving up its life.
The predator usually sits above its prey in the food chain, like the lion and the gazelle, the coyote and the rabbit or a household petand the wolf and the bison or other cloven hoof animals — ungulates — like deer and antelope. However, in common with many mutualisms, there is more than one aspect to it: A second example is that of the relationship between some ants in the genus Pseudomyrmex and trees in the genus Acaciasuch as the whistling thorn and bullhorn acacia.
The ants nest inside the plant's thorns. In exchange for shelter, the ants protect acacias from attack by herbivores which they frequently eat, introducing a resource component to this service-service relationship and competition from other plants by trimming back vegetation that would shade the acacia.
In addition, another service-resource component is present, as the ants regularly feed on lipid -rich food-bodies called Beltian bodies that are on the Acacia plant. Plants in the vicinity that belong to other species are killed with formic acid. This selective gardening can be so aggressive that small areas of the rainforest are dominated by Duroia hirsute. These peculiar patches are known by local people as " devil's gardens ".
The flowers die and leaves develop instead, providing the ants with more dwellings. 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.
Amensalism is an asymmetric interaction where one species is harmed or killed by the other, and one is unaffected by the other.
Competition is where a larger or stronger organism deprives a smaller or weaker one from a resource. Antagonism occurs when one organism is damaged or killed by another through a chemical secretion. An example of competition is a sapling growing under the shadow of a mature tree.
