Dandelions, horses, and other organisms that were brought by humans from one part of the world to another are examples of introduced species or exotic species. These organisms are often transported for various reasons, such as agriculture, trade, or companionship. While some may thrive in their new environments, others can become invasive, disrupting local ecosystems and outcompeting native species. This process highlights the impact of human activities on biodiversity and ecological balance.
