Dairy

Explanation:

According to the MyPlate Food Guide for teens, the smallest portion of a teen's diet should be dairy. Dairy includes products such as milk, yogurt, and cheese. The main contribution of these meals is calcium. On the other hand, the largest portion of the meal should be veggies, which are low on calories, high on fiber and contain many of the vitamins and minerals we need.

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
