Habitat selection refers to the process by which organisms choose their living environments based on various factors. These factors can include the availability of food, water, shelter, and mates, as well as the presence of predators or competitors. Different species have specific habitat preferences that help them thrive and reproduce. The choice of habitat can significantly impact an organism's survival and overall fitness. For example, birds may select nesting sites in trees that provide protection from predators, while fish might prefer certain water temperatures and depths. Understanding habitat selection is crucial for conservation efforts and managing ecosystems effectively.
