Question

the terrestrial biomes shown in the diagram above vary in net primary productivity. the explanation for the variation includes which of the following? i. temperature ii. precipitation iii. longitude a. i only b. ii only c. iii only d. i and ii only e. ii and iii only

Explanation:

Net primary productivity in terrestrial biomes is influenced by temperature and precipitation. Warmer temperatures and higher precipitation generally support more plant growth and higher net primary productivity. Longitude itself does not directly affect net - primary productivity in the way that temperature and precipitation do.

Answer:

D. I and II only
