Question

You have performed a litterbag experiment using a 10 g sample of pine needles in a coniferous stand at Coweeta. At the end of 0.80 years, the dry mass of your sample is 8.5 g. Calculate a value of k from these data. k = You have performed a litterbag experiment using a 10 g sample of pine needles in a coniferous stand at Coweeta.

Explanation / Answer

0.80x365 =292 days

(-k) = ln ('litter dry weight remaining'/'initial litter dry weight')/'number of days of exposure'

(-k) = ln (8.5/10)/292

(-k) = -0.00055

(k) = 0.00055-------------answer
