Concise Selina Solutions for Class 6 Biology Chapter 8 Habitat and Adaptation
Every organism has a unique ecosystem within which it lives. This ecosystem is its natural habitat. An adaptation is a modification or change in the organism's body or behaviour that helps it to survive. All organisms need to adapt to their habitat to be able to survive. It means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space. Adaptation is essential for the survival of living organisms. Animals, which are unable to adapt to changing environmental changes die. These adaptations are a result of genetic changes. Adaptation is the evolutionary process where an organism becomes better suited to its habitat. When people speak about adaptation, they often mean a 'feature' (a trait) which helps an animal or plant survive. An example is the adaptation of horses' teeth to grinding grass.
