Question

The terrestrial biomes shown in the diagram above vary in net primary productivity. The explanation for the variation includes which of the following? 1. Temperature 2. Precipitation 3. Longitude a. 1 and 2 only b. 1 and 3 only c. 2 and 3 only d. 1, 2, and 3

Answer 1

Terrestrial biomes differ in net primary productivity primarily due to two abiotic factors: temperature and precipitation, which place the correct answer as option a (1 and 2 only).

Step-by-step explanation:

Net primary productivity in terrestrial biomes is largely influenced by two major abiotic factors: temperature and precipitation. These factors have the greatest impact on plant growth, biomass production, and the variations in biomes across the planet. While longitude can affect climate to an extent, it is not typically considered a direct factor in determining the type of biome; therefore, it is less relevant to net primary productivity variation as compared to temperature and precipitation. The correct answer to the question about the variation in net primary productivity would be option a, which is 1 and 2 only, temperature and precipitation.
