What are the most productive and least productive ecosystems?

Globally, patterns of primary productivity vary both spatially and temporally. The least productive ecosystems are those limited by heat energy and water like the deserts and the polar tundra. The most productive ecosystems are systems with high temperatures, plenty of water and lots of available soil nitrogen.

What are the two most productive land ecosystems and the two most productive aquatic ecosystems?

Tropical forests and swamps are the most productive terrestrial ecosystems. Reefs and estuaries are the most productive aquatic ecosystems. All of these productive areas are in danger from human activity.

What are the three least productive habitats?

The biomes with the lowest levels of primary productivity include deserts, the tundra, the open ocean, and the lakes and streams biome. These biomes include habitats that have extreme temperatures and very limited precipitation, which results in very low production of new biomass.
