When comparing root systems of plants growing on a square foot in a corn field and on a meadow, what result do you expect to receive?

A) The mass and length of roots on a meadow will be larger because soil is poorer and there is higher diversity of plants.
B) The overall mass of roots on a meadow will be lower, but the length will be higher since roots need to grow deeper to reach nutrients.
C) The overall mass of roots will be identical in a cornfield and on a meadow.
D) The mass and length of roots in a cornfield will be larger because soil is fertilized.
