Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism).Because of the many linkages among species within a food web, changes to one species can have far-reaching effects.he keystone species concept is one of the best-known ideas in community ecology. Although it is true that many species potentially interact with one another in a food web such as depicted in Figure 1, in nature there are big players and little players. The biggest players of all are referred to as keystone species.
The 3 types of symbiotic relationships are mutualism, commensalism, and parasitism. What makes these three relationships similar is that they involve the close and often long- â¦ term interaction between different biological species. symbiotic relationship involves 2 species living together. Mutualism is when both benefit. Commensalism is when one benefits without harming the other. Parasitism is when on â¦ e species benefits while harming--but not killing--the other. An example of parasitism would be a tick on a dog.
