Final answer:
Tropical wet forests have high net primary productivity due to their ideal temperatures and precipitation values for plant growth. They have wet months with more than 30 cm of rainfall and dry months with fewer than 10 cm of rainfall. This climate allows plants to grow quickly and closely together.
Step-by-step explanation:
Tropical wet forests, also known as tropical rainforests, have high net primary productivity due to their ideal temperatures and precipitation values for plant growth. These forests receive an annual rainfall ranging from 125 to 660 cm (50-200 in) with significant seasonal variation. They have wet months with more than 30 cm (11-12 in) of precipitation and dry months with fewer than 10 cm (3.5 in) of rainfall. The climate in tropical wet forests supports the rapid growth of plants, which allows them to grow quickly and closely together.
