Final answer:
Visual processing and perception forms the base of the pyramid of adaptation through vision in children.
Step-by-step explanation:
The base of the pyramid of adaptation through vision in children is visual processing and perception. Processing of visual nerve impulses begins with interconnections in the retina and continues in the brain, where the optic nerve conveys signals received by the eye. This processing allows us to perform a vast number of functions, such as sense direction, movement, sophisticated colors, and distance.
