Polite reminder: Earth is a tree planet with some bacteria. Everything else is just the extra stuff that lives here too.
@InvaderXan What of marine life? Plankton, corals, sea grasses, and the like?
@dredmorbius Corals are types of cnidarian, and sea grasses are plants. Plankton are a huge collection of any kind of drifting ocean organism – with the exception of the terrestrial vertebrates, I'm pretty sure every group in this diagram contains some kind of plankton.
@InvaderXan As the diagram casts it, plants. Your original toot overspecified trees, to nitpick.
I'm wondering about biomass distribution and/or carbon fixation among primary producers.
