As stated previously, in a temperate climate, if a biodome is left uninsulated, the inner environment
of the biodome will have seasons, but further yet, any temperate deciduous vegetation within a
temperate biodome would drop its leaves to the ground every fall and thereby return nutrients to
the soil for re-use by any life form in its area the following springincluding itself. Regarding the
nutrients of these deciduous ecosystems, then, not only do fallen leaves add nutrients to the soil,
but fallen branches and fallen trees will also slowly decay in these ecosystems and return nutrients
to the soil. So these ecosystems are allowed to carry on within these biodomes just as they would
in their natural environments.
