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.
Sphere Interactions. The surface of the geosphere, where the rocky part of our planet is in contact with water, air, and/or life is generally where the spheres intersect and affect each other. The processes that move matter and energy from one sphere to another are called sphere interactions. Humans (biosphere) built a dam out of rock materials (geosphere). 2  Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (geosphere), or evaporating into the air (atmosphere).
