What is dinerism: definition and examples

Before addressing the concrete theme of dinerism, first we will quickly name some of the Types of interspecific relationships that occur in nature:

• DEPREDATION (Guepardo-Gacela): relationship in which an individual loses by the action of the other, that is, one of them dies to be food of the other, such as the gazelle in the indicated example.
• Parasitism (Dog – Flea): Use that is negative or harmful to the host individual.
• Mutualism (Bees – Flowers): Positive relationship for both parties.
• Competence (León – Leopardo): Relationship in which they have to fight to survive, it occurs when the forces of both are matched and one does not mean being a predator of the other.

If you want to learn more about interspecific relationships, their types and examples, enter this other post of ecology. In addition, you may also be interested in learning about the relationships between individuals of the same species and, for this, we advise you this other article on what intra -specific relationships are with examples.

Commentaryism is a type of biological interaction That occurs between two species or individuals, in which one of them benefits and the other is not harmed but also benefited, said colloquially “stays as it was.” If we transfer it to human beings and to name a daily action when we are hot, if a person is hot and fan and there is another person next to heat, it takes advantage of the air movement generated by the first person with his fan, something that does not affect him neither for good or for evil.

That is to say Commentaryism is a unidirectional relationshipwhere the individual who benefits is usually physically linked to the first individual, although there is also dinerism without being anchored, as in the case of scavengers. Here you can learn more about what are the scavenging animals.

The Types of dinerism They are established according to the benefit obtained. Next we will explain each of them:

Foresis

It receives the term of forest to the mechanical use of one individual with respect to the other, that is, forest is given when the smallest individual (usually) adheres to the host to move. It usually does not revert any problem to the host, it is also temporary. The tenant moves safely, without spending energy and can sometimes take advantage of the host food remains.

List

It occurs when the individual takes advantage of the organism so that it serves as “home.” In addition, the tenant goes beyond, it also defines the occupation of the home of another species or individual, such as a burrow used by another animal other than a rabbit.

Chemical dmentation

It occurs between bacteria, to be exact and that is clear, this type of dmentation occurs between two certain bacteria. The second does not tolerate a certain product of a metabolic process, but at this time the first intervenes, through its action it facilitates the tolerance of the second before this modified product.

If we stop to define more types of dinerism, we can refer to those that occur according to the need.

• Mandatory: The individual needs the other for his survival.
• Optional: In this case, the individual could survive without the other organism but in this way it is easier and with a lower energy expenditure.

Next, we expose the image table below the Examples of each type of dinerism so that in this way you can visualize more clearly what is explained above.

In the case of the example of the interspecific relationship known as foress and, more specifically, in the case between the shark and the rodas would also be worth the case of the optional type, since they could survive independently, but it is much easier for them to do so with the support of such a powerful animal.

After reading this ecology article, and complement it with others already published on our page, we hope it has served to solve all those doubts about it.
