Question

When comparing graphs of dry matter productivity (g/m2/yr) in different regions, which of the following is true?
a. Dry matter productivity is positively correlated with precipitation up to a limit.
b. Dry matter productivity has a direct, linear, positive relationship with temperature.
c. Temperature has a negative effect on primary productivity while precipitation has a positive effect on primary productivity.
d. Precipitation has a negative effect on primary productivity while temperature has a positive effect on primary productivity. e. The influence of temperature and precipitation act independently on the dry matter productivity.

Explanation / Answer

Ans :- Option E

i.e., when comparing graphs of dry matter productivity in different regions ,the influence of temperature and precipitation independently acting on the dry matter productivity is analysed.
