On the third time watching them, a lot of the details will start sinking in

Very good information! Thanks for posting them.
What needs to be pointed out though reef ecosystems work very differently. With sharks making up 50% to 80% of the fish biomass the trophic pyramid is inverted. And with corals and their holobiont animals are playing the role of autotrophs and are competing with algae for nutrients.

I think however that the base of the pyramid is still algal biomass, due to the 10% nature of nutrient absorption from level to level. There is much more algal biomass on a reef than there is coral+symbionts. Remember you also need to factor in phytoplankton.
