(Also, it's you're just stating a singe data point ("Bacteria have a biomass comparable to plants and animals") it's rather annoying to not actually state it and to instead just give a cite, forcing the reader to click on your link to find out something they could have just read. It's as if I had only said "Bacteria are different than termites" and had given you my link.)
