As we know, there are different types of relationships between living beings around the planet. In this world there is great biodiversity and, therefore, these living beings have to relate to each other and at the same time with the ecosystem. One of the relationships resulting from the interaction that occurs between the environment and living beings is the symbiosis. This symbiosis is responsible for the many forms of life that can exist in different habitats.
In this article we are going to tell you what symbiosis is both in ecology and biology and how important it is in relation to the relationship of living beings.
We can say that symbiosis is a close relationship of coexistence at the ecological level between two individuals of different species.
These individuals share the same ecosystem and are therefore in direct contact. Both species or have a benefit of the relationship that is established between one and the other.
The organisms involved in this type of relationship are called symbionts. These interactions were named by the German botanist Heinrich Anton de Bary in When we say that there is symbiosis between two or more species, we do not always have the same type of interaction.
There are various factors that occur between individuals and that make it essential for life. Not all cases of symbiosis have to leave the benefited species. 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.
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 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 pet , and the wolf and the bison or other cloven hoof animals — ungulates — like deer and antelope. Predation is also responsible for all kinds of evolution in the prey: developing means to hide from predators via mimicry, camouflaging and warning colors. Competition between species occurs when both entities vie for the same resources in the ecosystem.
This type of symbiotic relationship works in reverse; one or both organisms suffer because of the existence of each other. Invasive species upset the delicate balance in ecological communities when they procure the resources meant for the native organisms.
Yellow starthistle, for example, a native species of Europe, more than likely hitched a ride to the U. Because starthistle is a rapid-growing plant, it roots suck up all the water and nutrients, stealing these resources from the natural grasses, which often wither and die.
Even organisms of the same family can experience competition, like when the green anole lizard , a native of many Southern states, has to compete with the brown anole lizard for food sources and habitat, originally introduced to the region from Cuba.
The planet is replete with symbiotic relationships where two different species or organisms may interact, but neither experiences any type of evolutionary affect because of the other. An extreme example — stretching the limits of neutralism — and offered by the University of Miami, includes the Bacterian camel and the Long-Tailed Tadpole Shrimp, both of whom may come in contact in the Gobi Desert with negligible effects on either.
The importance of symbiotic relationships to all living organisms on the Earth cannot be understated. All across the globe, in every ecological community in the world, from those viewable with the naked eye to those only seen under the lens of the microscope, symbiotic relationships remain crucial to maintaining balance in nature's multiple processes. Symbiotic relationships cross taxonomies and species and involve most all living creatures on the planet in some way or another.
Symbiotic relationship help to provide people with food, populate the planet with trees and plants, and keep animal and plant populations in balance. Symbiotic relationships can help individual species to evolve or change and even thrive. Without symbiotic relationships, there would not be any coral reefs, trees might not proliferate as far and wide as they do, aided by the birds and insects that transport seeds afar, and even human beings might not have survived long enough to evolve into Homo sapiens — Earth's modern humans.
As a journalist and editor for several years, Laurie Brenner has covered many topics in her writings, but science is one of her first loves.
Her stint as Manager of the California State Mining and Mineral Museum in California's gold country served to deepen her interest in science which she now fulfills by writing for online science websites. Brenner is also a published sci-fi author.
Our goal is to generate a compendium of studies that highlights the role of symbiosis in shaping biodiversity patterns and establish how symbiotic relationships are primordial to understanding species distributions, as well as how symbiotic relationships can buffer biodiversity loss during climate change.
