The annual net primary productivity of the whole biosphere is approximately 104.9 petagrams of carbon per year. This is the total amount of carbon that is fixed per year through photosynthesis by plants, minus the amount of carbon that is lost per year through plant respiration.

Here are the steps to understand this:

1. Primary productivity is the rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances.

2. The total amount of primary productivity in the world is referred to as the gross primary productivity (GPP).

3. However, a significant amount of this energy is used by plants for their own metabolism and growth (respiration). The energy that remains after these processes is referred to as the net primary productivity (NPP).

4. The NPP is the available biomass that is available for consumption by heterotrophic organisms (animals, fungi, microorganisms).

5. The annual net primary productivity of the whole biosphere is estimated to be approximately 104.9 petagrams of carbon per year. This is a measure of the total amount of new biomass created by plants each year.

6. This value is important as it gives us an idea of the total amount of energy that is available to support life on Earth.
