(D) Photosynthesis is a biological process that utilizes water as a source of electrons and protons. Scientific estimates suggest that the total amount of water present on Earth is approximately $1.386 	imes 10^9 \ km^3$. Based on the global rate of photosynthesis,it is calculated that the total volume of water split by all photosynthetic organisms on Earth over a period of $2$ million years is approximately $25$ million $km^3$. Therefore,the correct option is $D$.

The approximate amount of water on Earth that is split by photosynthesis once every $2$ million years is:
