Give me an example of a case where the branches of natural science appear to overlap

There are numerous example wherein the branches of natural science appear to overlap. The fields include, biophysics, biochemistry, biopsychology, neurophysics, geochemistry, and etc. these sciences that are clustered majorly as chemistry, physics, biology, geology and other major sciences are aggregated into a subbranch that are now cross-sciences because with the help of one spectrum or field it can also support and explain other certain phenomemons like why do living creatures eat (Biology) and what do they eat what are then the molecular compositions or atomical compositions of these goods (Chemistry), and in plants why does some plants bend and how much in order to attain sunlight (Physics and biology) and lastly, what type of soil do most plants or creatures adapt to (Geology).
