Is the temperate deciduous forest highly productive?
Temperate Deciduous Forest Biome Net primary productivity ranges from 600–1500 g m-2 yr-1 with high litter production. Litter serves as a major pathway for nutrient recycling. This biome is named for the dominant trees that drop their leaves during the winter months.
Which biome has the most agriculture?
Desert is the largest of the biomes. It is only in the tropical rainforest that water and temperature are continuously favorable for plant growth. This makes it the most diverse and productive biome. There can be as many as 10,000 species of plant per hectare.
