Question

Quizplus · Accepted Answer

The low productivity of arctic tundra ecosystems is due to a combination of factors including low evapotranspiration, which limits the availability of water, and low-nutrient soils, which limit the availability of essential nutrients for plant growth. These conditions together contribute to the overall low productivity of these ecosystems.
