Organisms that can only survive in specific environments are referred to as specialists. These species have adaptations that enable them to thrive in particular ecological niches, often with limited tolerance for environmental variation. For instance, some plants might be adapted to arid deserts, while others can only be found in specific freshwater habitats. Specialists contrast with generalists, which can live in a broader range of habitats and adapt to varied environmental conditions. The specificity of specialists often makes them more vulnerable to changes such as habitat destruction and climate change, as they depend on a very narrow set of living conditions to thrive.
