Types of Population Interaction
In nature, all organisms and their populations interact with one another to some degree or the other. That is how an ecosystem works perfectly! This population interaction is generally between two different species populations. These interactions can be beneficial or neutral or detrimental. Accordingly, there are six types of population interaction.
The different ways populations of two different species interact with each other can be summarized under the following headings.
Mutualism
When the two different population species interact in such a manner that it is beneficial to each other, then this form of interaction is called mutualism. Lichens are a classic example of mutualism in between fungi and algae. Even plants and animals show good mutualism.
Plants need some agents for pollination and seed dispersal. And these agents are the animals. Animals, in turn, are rewarded with the nectar or the fruits of the plants. But, even in mutualism, there are some cheater species, which may not reward the other species. This leads to co-evolution of the species.
Competition
When the closely related species fight for limited resources, there is a competition between the species. These types of interactions are called competition. This fight for resources can occur between diverse groups of the population also.
Competition can occur even when there is an unlimited supply of resources. Here, it depends on the superiority of one species over the other. In the presence of one population species, the other population species may not use the resources effectively. But if the dominant species is removed, then the other species will use the resources to their full capacity.
Predation
This interaction is a very important one as it ensures that there is stability in the ecosystem. The two main populations interacting in predation are the predators and the prey.
Without the predators, the prey population will go out of control. The species diversity in a community is also maintained by the predators. They reduce the intensity of the competition between prey species. The prey species have also evolved several mechanisms to lessen the impact of predation.

Parasitism
This is an interaction of populations where a parasitic mode of nutrition is clearly seen, with one species being completely dependent on the other host species for all its meals/ nutrient requirements. Parasitism is clearly seen in many taxonomic groups, right from plants to higher vertebrates.
