Answer

Brief Explanations:

Indirect observation involves observing signs of organisms (like tracks, nests) without directly interacting with or disturbing them. Mark/recapture requires handling animals, direct observation can be intrusive, and sampling may involve collecting specimens. Indirect observation is thus the least invasive.
