Symbiosis: definition

DEFINITION

Symbiosis refers to a close and lasting relationship between two different organisms. This relationship can take several forms: sharing a habitat, cooperation for reproduction, provision of nutrients, etc. The best-known examples of symbiosis are the relationships between plants and animals. Certain plants (e.g. trees) provide habitat for animals (birds, insects, etc.). In exchange, the latter contribute to the pollination of plants or their defense against predators.

Definition of Symbiosis and Examples of Different Types of Symbiosis

Symbiosis is an intimate relationship between two different organisms that mutually benefit from their association. Symbionts can be bacteria, algae, fungi, animals or plants. Symbiosis is often necessary for the survival of one or other of the organisms involved.

There are different types of symbiosis:

– Parasitic symbiosis is a relationship in which one organism (the parasite) benefits from the association, while the other (the host) suffers negative consequences. Examples of parasitic symbiosis include the relationships between certain insects and the plants they feed on, as well as the relationships between certain animals and their parasites.

– Mutualistic symbiosis is a relationship in which both organisms benefit from their association. Examples of mutualistic symbiosis include the relationships between bacteria in the digestive tract of animals and the animals themselves, as well as the relationships between plant roots and the microscopic fungi that surround them.

– Commensal symbiosis is a relationship in which one organism benefits from the association, while the other receives neither benefit nor harm. Examples of commensal symbiosis include the relationships between human skin bacteria and humans, as well as the relationships between certain fish and the sharks that host them.

– Symbiotic symbiosis is a relationship in which both organisms benefit from their association and are dependent on each other for survival. Examples of symbiotic symbiosis include the relationships between algae and corals, as well as the relationships between bacteria in the digestive tract of animals and the animals themselves.

Symbiosis is a concept that designates a close and intimate bond between two living beings. This can take the form of a mutually beneficial relationship, as in the case of plants and animals that feed on each other, or a subservient relationship, as in the case of parasites that live at the expense of their host.

In nature, there are many examples of symbiosis. The best known are undoubtedly the relationships between bees and flowers, or the relationships between whales and crustaceans. But symbiosis is also present in many other organisms.

Plants and animals are often symbiotic. Plants provide oxygen and food to animals, and animals in turn provide nitrogen and fertilizer to plants. This relationship is essential to the survival of many species.

There are also many forms of symbiosis between animals. Animals of the African savannah, for example, live in symbiosis with ants. Ants protect animals from predators and parasites, while animals provide ants with food and shelter.

Symbiosis is a concept that allows us to better understand the nature and place of living beings in the ecosystem. It is also an important concept in biology, because it helps us understand how different species can coexist and maintain life.

Symbiosis refers to a close relationship between two different organisms that is beneficial to both parties. There are different types of symbiosis, such as commensality, heterosymbiosis and homeostasis. Finally, examples of symbiosis are found everywhere in nature, such as between plants and fungal symbionts, or between animals and bacteria.
