Question

1. define evolution and adaptation. explain how they are related.

Explanation:

Evolution is the process of change in all forms of life over generations, mainly through mechanisms like natural selection. Adaptation refers to the process by which organisms become better suited to their environment, either through genetic changes (structural/physiological adaptations) or behavioral adjustments. Adaptations are crucial for evolution as they increase an organism's chances of survival and reproduction. Over time, the accumulation of beneficial adaptations in a population leads to evolutionary changes. For example, if a population of birds has individuals with slightly longer beaks (an adaptation) that help them access food more easily in their environment, those birds are more likely to survive, reproduce, and pass on the gene for longer beaks. As this happens over generations, the population's beak length (a trait) evolves.

Answer:

Evolution is the change in life - forms over generations (e.g., via natural selection). Adaptation is organisms' adjustment to the environment (genetic/behavioral). They are related as adaptations drive evolution: beneficial adaptations increase survival/reproduction, and their accumulation in a population causes evolutionary change (e.g., bird beak length evolution due to food - access adaptation).
