Interactions refer to the ways in which individuals or groups communicate and engage with one another. These exchanges can occur through various forms, such as verbal conversations, written messages, or non-verbal cues like body language. Interactions are essential for building relationships and understanding different perspectives. In the context of social media, interactions often involve likes, comments, and shares, allowing users to connect with others across distances. In science, interactions can describe how different elements or organisms affect one another, such as in ecosystems where species rely on each other for survival.
