Answer: The study of plant varieties.
Explanation:
This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.
Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.
He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.
I am pretty sure that biologists use molecular clocks to try to measure <span>when two species separated from a shared ancestor. Do hope you still need the anwer because this one is definitely correct, do not hasitate to use it! Regards.</span>
Explanation:
The quantity of energy decreases down each trophic level as only 10% of the energy at the upper level is transferred to the next level, the remaining 90% is lost as heat during metabolic process. Through the energy pyramid we can explain how energy is lost at each trophic level, the number of consumer at each trophic level that will benefit from the transfer of energy depends on the size and quality of the energy from the autotrophs
