Answer:
Biomass on the seafloor, and greater quantities near the poles
Step-by-step explanation:
Snelgrove says this phrase to explain and debunk a common myth in education, that there needs to be oxygen for animals to live. Snelgrove focuses on the sea creatures that live deep down like the blobfish, he says these organisms were able to adapt to places with no oxygen.
He then explains that if all the water was sucked out of the ocean we will be left with biomass on the seafloor and in special high quantities in the poles, where the conditions are seemingly not ideal for organisms, but in the deep sea, this is where there are more living organisms and biomass. This phenomenon is explained by the adaptations of the organisms to their surroundings, and mainly due to the nutrients present on the seafloor which are the starting point of the food chain in the seas..
