[Spoilers, I guess]
From the text dump:
"The Food Web has
three levels,
each consisting of
three plants (in ascending size),
two plant-eaters, and
a predator. Add new plants and animals, in the right order, to stabilize or increase the T-score of a planet.."
Looks like 9 creatures and nine plants from here. Sorry buddy.
EDIT: Additional confirmation, check the top-right corner of this screenshot (View picture if it's too small):
