Sorry, I need to apologize.
My statement that "In general, linear models work well for biological
growth curves with small to medium sized data", may not be correct.

The presence of non-linearity (in x) does not necessarily mean that
you can't use a "linear model".

I conducted an experiment where earthworms were subjected to two treatments,

12 days for 398 days and the biomass growth curves as a function of time were
plotted.
There was clearly a non-linear growth pattern such th
