In grassy habitats, you have fields of decaying material vs woody plant
habitats, more of the nutrients are locked up in living tissues. No? How
much of a woody plants biomass is locked up in woody tissue vs deciduous
tissues? I guess that it would be different for each species of course, but
I guess that's my question. It seems to me that forest/scrubby areas would
retain more nutrients in living woody tissue year round and grassy/prarie
habitats would have a larger influx of nutrients to the water due to a
larger percentage of decaying material.
