Competition refers to the rivalry between individuals or groups vying for the same goal or resource, often within a specific market or environment. In economics, competition occurs when various businesses strive to attract customers by offering better price, quality, or service than their rivals. This process drives innovation, efficiency, and consumer choice, as companies work to gain a competitive advantage.

In ecology, competition describes the interactions between organisms seeking the same essential resources, such as food, water, or territory, which can influence population dynamics and species distribution. There are two main types of ecological competition: intraspecific (within the same species) and interspecific (between different species).

Overall, competition is a fundamental concept that shapes various systems, from markets to ecosystems, highlighting the interplay and conflict of interests in the pursuit of limited resources.
