What is an interspecific mutualism?

Mutualisms, interspecific relationships beneficial to both organisms involved, are also of great ecological significance in soils.

What is facultative mutualism?

In facultative mutualism, the partners may coexist without a depending on each other. They, however, form a diffuse relationship involving a varying mixture of species. For example Honeybees and plants.

What is a symmetric mutualism?

Consider two populations in a symmetrical mutualism where each population consumes a resource produced by the other population: species 1 consumes resource 1 and produces resource 2, while species 2 consumes resource 2 and produces resource 1. Assume also that the two resources are also supplied by other processes.

What are the different types of interspecific interactions?

The main types of interspecific interactions include competition (-/-), predation (+/-), mutualism, (+/+), commensalism (+/0), and parasitism (+/-).

Which of the following interactions can be intraspecific?

i) Intraspecific interaction: Interaction between the individuals of same species is known as intraspecific interaction. E.g.: Cannibalism. 2) Interspecific interaction: Interspecific interaction arises from the interaction of population of two different species.

Is commensalism a symbiosis?

Commensalism is a type of symbiotic relationship in which one species benefits, while the other species is neither harmed nor helped.

Is lichen a mutualistic relationship?

Like all fungi, lichen fungi require carbon as a food source; this is provided by their symbiotic algae and/or cyanobacteria, that are photosynthetic. The lichen symbiosis is thought to be a mutualism, since both the fungi and the photosynthetic partners, called photobionts, benefit.

Is obligate a mutualism?

In obligate mutualism, one organism cannot survive without the other. This term is easy to remember because both organisms are obligated, or forced to, rely on one another. An example of obligate mutualism is the relationship between ants and the Acacia plant. The plant provides food for the ant, as well as shelter.
