To simplify the process, convert each given weight into standard notation:
Lion:
![1 * 10^(5) = 1 * 100000 = 100,000 g](https://img.qammunity.org/2021/formulas/mathematics/high-school/istu2k92vjtq1c2oqfreptpo49u4sr5575.png)
Ant:
![2 * 10^(-3) = 2* 0.001 = 0.002](https://img.qammunity.org/2021/formulas/mathematics/high-school/y75ddzkqaoqfxb9z7mns4drw2cvacdltbb.png)
Divide the ant's weight from the lion's weight:
![100000 / 0.002 = 50,000,000](https://img.qammunity.org/2021/formulas/mathematics/high-school/fxw9d2f6e7839nz55wkacoqmicq1blwf3k.png)
Convert to scientific notation: (use # of zeros to determine exponent)
Therefore, the correct answer is C.
