A2 Biology - Ecological efficiency (OCR A Chapter 23.2)
As energy is passed along the food chain through feeding, some of the energy is lost through various ways, hence we say ecological efficiency is never 100%. Here we will discuss why there is always energy loss as we pass from one trophic level to the next and how we can maximise the energy transfer efficiency.(This video is an immediate continuation from the video on trophic levels and biomass.)Please subscribe for more content and comment below to let me know what you think! :)Facebook: BioRach - A-level Biology Online@BioRachProjectmusic:"Dreaming in 432Hz" by Unicorn Heads

She chose to remember the good memories and not the bad.
