Which of the following terrestrial biomes has the highest primary productivity per unit area? a. arctic and alpine tundra b. desert c. grassland d. temperate deciduous forest e. tropical forest

e. tropical forest

Explanation:

The tropical forests are the terrestrial biomes that have by far the highest primary productivity per unit area. The reason for this is that these forests are located around the Equator, so they are getting constant sunlight at direct or nearly direct angle, and the precipitation levels are very high.

Having constantly warm weather and lot of water, means that it is a perfect place for the development of the producers, such as the plants. They are so abundant at this areas that it is not even comparable with the other terrestrial biomes.

The sheer abundance of the plants in the tropical forest biome means that the primary productivity per unit area is enormous. That enables the development and existence of millions of other organisms, making this biome extremely rich in biodiversity.
