<< I also think it the beetles form an integral part of the svannah
ecosystem; without them the dung would not fertilize the soil as
quickly and the open grasslands would not be possible (note the neat
loop here: grasslands suit grazers, grazers produce dung, dung helps
the beetles and makes the grass possible; once started it is
self-supporting).

How would the dung fertilize the soil if the beetles ate all the dung? Also,
if the dung did fertilize the soil, thats all the mushrooms need to grow
from.
