What could happen if scientists did not compare results ?

Hmm.

Explanation:

Publishing results of research projects in peer-reviewed journals enable the scientific and medical community to evaluate the findings themselves. It also provides instructions so that other researchers can repeat the experiment or build on it to verify and confirm the results.

TL; DR, Basically to confirm the results.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
