6 Types of Symbiotic Relationships EXPLAINED (with examples)” is published by Ernest Wolfe in btcmu.infoion. Do not include the definitions yet. First, ask students to identify the root words and brainstorm what types of ecological and symbiotic relationships the terms. Symbiosis is any type of a close and long-term biological interaction between two different Endosymbiosis is any symbiotic relationship in which one symbiont lives within the tissues of the other, either within the cells or extracellularly. A non-obligate symbiosis is seen in encrusting bryozoans and hermit crabs.
The bee collects nectar from the flower using a long, straw-like proboscis to suck the sweet fluid into a separate sac called a nectar or honey sac for later use in the colony as food.
While the bee moves about the flower, pollen collects on its furry legs and body. When the bee leaves the flower to land on the next one, the pollen falls or rubs off onto the next flower, resulting in pollination. The flower helps the bee by giving it nectar, and the bee helps pollinate the flower by moving pollen from flower to flower.
A Mutualistic Relationship The relationship between ants and aphids, for example is a mutualistic one defined as defensive symbiosis. The ant acts like shepherds over the aphids.
Aphids provide honeydew for the ants, and the ants herd the aphids into their shelter at night for protection against predators, escorting them back outside in the morning. Some ant species are even known to take aphid eggs into the nest's storage chambers during the cold winter months.
Symbiosis - Wikipedia
Often called ant cattle, sometimes ants remove the wings from aphids to keep them from flying away. The ants may also release chemicals that cause the aphids to become more docile.
One Organism Cannot Survive Without the Other Another type of mutualistic relationship — obligate mutualism — exists when each individual species cannot survive without the other. An example of this occurs between termites and their intestinal flagellate symbionts — prokaryotic organisms with whip-like flagella or appendages that help them move. The organisms within the termite help break down the dense sugars in wood so that the termite can digest it.
But termites also have other symbionts in their innards that work in cooperation with each other and the termite.

Without this relationship, termites and their inner guests would not survive. Not Obligatory, but Beneficial to Both The clown fish and the anemone represent protocooperation symbiosis, a relationship that benefits both, but unlike the termite's and its symbionts, both can survive independently of the other. The fish has a home within the fat, wavy arms of the anemone that protects the fish from predators; the fish also protects the anemone from its predators and sometimes even brings it food.
Cells Living in Other Cells When one organism lives inside the tissue or cells of another, biologists define that as endosymbiosis.
For the most part, these relationships are the norm for many unicellular entities. For example, a unicellular eukaryotic a cell with an encased nucleus inside it organism Paramecium bursaria serves as a host to eukaryotic Chlorella algae cells.
The alga produces energy via the photosynthesis process, and the paramecium benefits as it receives some of that energy or food. Additionally, the algae reside inside a protected, mobile home — the body of the paramecium.
Organisms That Live on the Surface of Another Another kind of mutualistic symbiosis involves one organism living on the skin or surface of another in a mutually beneficial relationship. Leaf cutter ants have a special symbiont, a type of unicellular bacteria that lives on their skin. Leaf cutter ants bring the cut foliage back to the colony where they inject it with a special type of fungus.
The fungus serves as a food source for the colony, which the bacteria protect from other invading fungi species. 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. 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. The mature tree can rob the sapling of necessary sunlight and, if the mature tree is very large, it can take up rainwater and deplete soil nutrients.
Throughout the process, the mature tree is unaffected by the sapling. Indeed, if the sapling dies, the mature tree gains nutrients from the decaying sapling. An example of antagonism is Juglans nigra black walnutsecreting juglone, a substance which destroys many herbaceous plants within its root zone.Symbiosis: Mutualism, Commensalism, and Parasitism
