PLEASE HELP 30 POINTS AND BRAINLIEST FOR BEST ANSWER (YOU DON'T HAVE TO BE FIRST TO GET BRAINLIEST) What biomes have high NPP? Low NPP? Why?

Net Primary Productivity is affected by temperature, water availability, carbon dioxide, and nutrients, all of which are abiotic factors. In Tropical Rainforests, water, sunlight, and high temperatures are consistent and a dense concentration of plants is present, causing both the GPP and NPP to be very high.Several biomes, including tropical savannas, boreal forests, and temperate grasslands have moderate levels of primary productivity due to less precipitation and varying temperatures. The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome.
