Productivity Comparisons among

Biomes and Aquatic Ecosystems

(plant growth / area / time) ~ (g/m2/yr)

Net Primary Production = Gross Primary Production - Respiration

Terrestrial

Tropical Rainforest - 2,200

Temperate Forest - 1,200

Temperate Grassland - 600

Tundra - 140

Desert - 90

Aquatic

Coral Reefs - 2,500

Estuaries - 1,500

Upwelling Zones - 500

Open Ocean - 125

• Think about why we see this gradient, and the factors

limiting production in terrestrial vs. aquatic ecosystems
