Answer:
E
Explanation:
They need energy to do all these necessary feats.
6-C (breaks off)
7-C(they secrete acid that breaks away rocks)
Phosphorus is, therefore important in cell division and development of new tissue.
It is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.
Hopefully this helps :)
