Answer:
Coccus is suitable for dry environment and a rod is better adapted for moist environment.
Explanation:
The probability of Coccus would be better suitable for a environment which is dry. A sphere posses less surface area for the volume, as such, moisture which is lost through osmosis is less in dry environment conditions.
During a moist environment, the ratio of the surface area to volume of a rod shaped bacterium is high, which allow higher efficiency to transfer water and solutes into and outside of the cell, and to make possible for a cell which is in rod shaped, have a metabolic rate higher.
