Detailed explanation-1: -Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits.

Detailed explanation-2: -Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Detailed explanation-3: -Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.

Detailed explanation-4: -To scientists, an adaptation is any characteristic that helps an organism survive or reproduce. Adaptations can be physical as well as behavioral. Most adaptations happen slowly-they are traits that are inherited over many generations. Examples of traits include the size and shape of a bird’s beak.

Detailed explanation-5: -Answer: Solution: Air, water, climatic conditions, temperature, plants, animals living in that area all affect the habitat. For example: Organisms living in a desert are adapted with specific characteristic like the plants have leaves modified into spines to prevent excessive loss of water.
