Keystone species play a critical role in maintaining the structure of an ecosystem or community, despite not always being the most abundant species. Their loss can lead to significant changes in the community structure.
Mutualism is a type of symbiotic relationship in which both species benefit. Examples include bees pollinating flowers while obtaining nectar.
Community ecology focuses on how different species interact with each other within a given area, including competition, predation, and symbiosis.
Competitive exclusion occurs when two species compete for the same resources, and one species outcompetes the other, causing it to be driven to extinction in that environment.
Herbivory refers to the interaction where an organism feeds on plants. In this case, the cow eating grass is a classic example of herbivory.
