Kohastumused are adaptations that enable organisms to survive and reproduce in their specific environments. These can be structural, physiological, or behavioral. Structural adaptations are physical characteristics, such as the thick fur of a polar bear for insulation or the streamlined body of a fish for efficient swimming. Physiological adaptations involve internal processes, like the ability of a desert plant to store water or the venom production in a snake to subdue prey. Behavioral adaptations are actions an organism takes to survive, such as the migration of birds to warmer climates or the hibernation of a bear during winter.

The process of adaptation occurs through natural selection. Organisms with traits that are better suited to their environment are more likely to survive, reproduce, and pass on those advantageous traits to their offspring. Over many generations, these beneficial adaptations become more common within a population. For example, if a population of insects is exposed to a pesticide, those individuals with a natural resistance will survive and reproduce, leading to a population that is largely resistant to that pesticide.

Adaptations are crucial for the biodiversity of life on Earth. They allow species to exploit a wide range of ecological niches and to thrive in diverse and often challenging conditions. The intricate relationships between organisms and their environments are a testament to the power of adaptation.
