Mutualism (biology) - Wikipedia
Relationships Between Organisms. No other species care that this lichen lives on this rock. Everything on Earth doesn't exist in its own little bubble. Species. The interaction among organisms within or between overlapping niches can be On top of these, mutualistic relationships have three general purposes. Symbiosis is a relationship between two organisms: it can be mutualistic (both In microbiology, there are many examples of mutualistic bacteria in the gut that.
Strict service-service interactions are very rare, for reasons that are far from clear. 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.►10 Incredible Organisms Working Together In Nature◄
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. Another type of Allomerus sp.

In this non-taxonomic context one can refer to "same-species groups" and "mixed-species groups. For example, zebra Equus burchelli and wildebeest Connochaetes taurinus can remain in association during periods of long distance migration across the Serengeti as a strategy for thwarting predators. Cercopithecus mitis and Cercopithecus ascaniusspecies of monkey in the Kakamega Forest of Kenyacan stay in close proximity and travel along exactly the same routes through the forest for periods of up to 12 hours.
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. Whilst the presence of the grass causes negligible detrimental effects to the animal's hoof, the grass suffers from being crushed.
