Explanation:
Phonemic awareness is very important as the readers have to know how the letters represent the sound. This is how readers have access to reading new words and to understand the alphabetical principle.
Comprehension is the activity that is used for phonemic awareness. We understand the word if we understand it as a line of phonemes or separate sounds.
