Adaptations help organisms survive in their environment from "summary" of NCERT Exemplar Problems-Solutions BIOLOGY class 12th by Arihant Experts
Adaptations play a crucial role in the survival of organisms in their respective environments. These adaptations are specific traits or characteristics that have evolved over time to help organisms effectively cope with the challenges posed by their surroundings. By possessing these adaptations, organisms are better equipped to obtain food, avoid predators, find mates, and reproduce successfully. One of the key ways in which adaptations aid in survival is by enhancing an organism's ability to obtain food. For example, the long neck of a giraffe allows it to reach leaves high up in trees that other herbivores cannot access. This gives the giraffe a competitive advantage in environments where food may be scarce at ground level. Adaptations also help organisms avoid predators. Camouflage, for instance, allows certain animals to blend in with their surroundings, making it harder for predators to spot them. This increases their chances of survival and enables them to pass on their genes to the next generation. Furthermore, adaptations can aid in the process of finding mates and reproducing. Brightly colored feathers in birds or elaborate courtship displays in certain species are examples of adaptations that help individuals attract mates. By successfully reproducing, organisms ensure the continuation of their genetic lineage. In essence, adaptations are the result of a long process of natural selection, where individuals with beneficial traits are more likely to survive and pass on those traits to their offspring. Over time, these adaptations become more common in a population, leading to a better fit between organisms and their environments.- Adaptations are essential for the survival of organisms in their environment, as they provide them with the tools they need to thrive and reproduce successfully. Through the process of natural selection, organisms continually evolve and adapt to changing conditions, ensuring their continued existence in a dynamic world.
