In what situations would sampling work best for estimating population size, in what situations would mark and recapture work best and why?

Well, I wrote that the sampling technique would work best for estimating population size in a place were the organisms are in a few small ares. (I'm most likely wrong, don't take my word for it) I know I didn't answer it all but something's something.

Sampling works best for immobile organisms
whereas mark and recapture would work best for mobile organisms.
Sampling works best when attempting to count a large population of immobile organisms in a small area. It allows less counting and since organisms are immobile there is less chance to meet an unusual distribution (not even) in a small area. Mark&recapture method works best with a large population of organisms that are for whatever reason unseen but move a lot. The last will allow for a better mix of tagged individuals with the rest of the population which will lead to more accurate results in the second sample. Due to this, the unseen portion of the population that is usually miscounted can be included and considered too.
Normally, the sampling method works best in ares with big populations.
