Question

What living organism has the biggest population on earth

Answer 1

Since this question is in zoology, I expect that you want to know which animal has the biggest population?  The answer is not ants, but another arthropod - copepods.  Copepods are tiny crustaceans that live in marine and freshwater environments.  While you can find areas on land without ants, you'd be hard pressed to find water without copepods.

"Small planktonic marine copepods (< 1 mm in length) are the most abundant metazoans on Earth." - Turner, Zoological Studies 43(2): 255-266

"it is estimated that there are more individual copepods on the planet (1.37 × 1021) than there are insects" - Geoffrey Allan Boxshall, PhD

Answer 2

Not counting microbes it's ants.

Edit: One estimate is 4 quadrillion ants, which is 4,000,000,000,000,000 ants. They average 15-20% of the total terrestrial animal biomass, and up to 25% in tropical areas.
