Which terrestrial biomes has the highest net primary productivity?

Forest has the highest productivity

Explanation:

The tropical rain forest ecosystem has the highest average net primary productivity. The open oceans account for most of the net primary productivity on the planet even though they have one of the lowest average net primary productivities because they cover by far the most area on earth (65%).Net primary productivity, or NPP, is gross essential profitability less the pace of vitality shortfall to digestion and upkeep. At the end of the day, it's the rate at which vitality is put away as biomass by plants or other essential makers and made accessible to the purchasers in the biological system.  Net primary productivity changes among environments and relies upon numerous variables. These incorporate sun based vitality information, temperature and dampness levels, carbon dioxide levels, supplement accessibility, and network cooperations (e.g., grazing by herbivores These variables influence what number of photo synthesizers are available to catch light vitality and how productively they can play out their function). Total primary production in an ecosystem is known as the ecosystem's gross primary production (GPP).

They don’t store and transmit heredity

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
