What is slowed when water is a limiting factor in an environment?

A. amount of evaporation

B. population growth

C. the types of rocks

The most probable answer between these three for this problem would be B. Population growth.

Though the types of rocks are also affected when water is a limiting factor, there would only be other types of rocks that would arise which takes into account that water is a limiting factor. The amount of evaporation, on the other hand, would also be affected. The population growth, however, would be greatly affected that it would be slowed down since population growth greatly depends on the essentials of maintaining life where water lies as one of the main factors of promoting life. When water is a limiting factor, population growth would surely decrease and is slowed down.
