Description
From my reading of the code it seems like the [q10_mr parameter](https://github.com/ESCOMP/CTSM/blob/alpha-ctsm5.4.CMIP7.09.ctsm5.3.068/src/biogeochem/CNSharedParamsMod.F90#L92-L95) is used by both [heterotrophic respiration](https://github.com/ESCOMP/CTSM/blob/0991175998c94291f3d544169e3a4acb71b0b7f1/src/soilbiogeochem/SoilBiogeochemDecompCascadeBGCMod.F90#L610) in Century AND [plant maintenance respiration](https://github.com/ESCOMP/CTSM/blob/alpha-ctsm5.4.CMIP7.09.ctsm5.3.068/src/biogeochem/CNMRespMod.F90#L222) (stem, coarse root, fine root, but not leaf).
Is this as intended? Would it be appropriate to separate into two independent parameters?
Note: this is also how q10_mr is used in FATES.
Contributor guide
Research direction
Read the q10_mr definition in src/biogeochem/CNSharedParamsMod.F90 and compare its uses in SoilBiogeochemDecompCascadeBGCMod.F90 and CNMRespMod.F90. Review the corresponding FATES usage noted in the issue. Done means reaching and documenting a decision on whether the parameter should remain shared or be separated, with affected references addressed if needed.
