Similarly, with biological systems. If you take parts of them out of
the system, they behave differently in a different environment than when
they are left in the integrated system. The way they behave in the
integrated system is "downhill" as the 2nd law constrains the system's
overall behavior. The *different* way they behave when isolated from
the other biological structures is also "downhill" since the different
environmental conditions redefine just what it means to *be* "downhill"
in the different context. In neither case is the 2nd law "overcome".

Yes! A carpenter takes a pile of lumber and builds a house. Entropy
increases. The BTUs the carpenter burns while building the house can
never be recovered Once the lumber is used it can't be used again without
first tearing it down and building a pile of lumber.
A leaf "uses" solar radiation to convert CO2 into wood. It is an
irriversable process and entropy is decreased. For that matter, God uses
magic to convert dust into Adam. Entropy still increases. Doesn't matter
that God has an infinate heat source.
