The difference in concentration between solutions on either side of a cell membrane is a concentration gradient.
In the field of biology, a concentration gradient can be described as a difference in the concentration of molecules inside and outside of a cell. It is due to concentration gradient that molecules move into and out of a cell through the cell membrane.
Some molecules move from an area of higher concentration gradient to an area of lower concentration along the concentration gradient. Diffusion is an example of such a process.
On the other hand, some molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Active transport is an example of such a process.

Answer:
<em>C. Increased loss of soil nutrients</em>
Explanation:
The practice of leaving crop residues on the field in between planting seasons is known as conservation tillage.
<h3>Conservation tillage</h3>
Some soils are prone to erosion once they are directly exposed to the impact of precipitation.
After harvesting crops from a field, the crop residues are left on the field to prevent the direct impact of precipitation in cause erosion. The crop residue, in addition, adds to the organic matter of the soil after their decomposition.
Such a practice is known as conservation tillage.
