Calculate the average decomposition constants for all species collectively within each group (native and invasive; calculate the SE of the mean as well; see the Stats Review in canvas for help remembering what is the SE). Is the mean decomposition rate higher for invasive species compared with native species, taking the variation in means among species (SE of the mean) into account?
A) Yes, the mean decomposition rate is higher for invasive species.
B) No, the mean decomposition rate is higher for native species.
C) Cannot be determined from the information provided.
D) Both native and invasive species have the same mean decomposition rate.
