| 1. | Terrestrial freshwater ecosystems generate about 1.5 % of the global net primary production.
|
| 2. | The energy remaining after respiration is considered the net primary production.
|
| 3. | They generate 32 % of the world's net primary production.
|
| 4. | Dmitri thought that the primary production can be broken down into gross and net primary production.
|
| 5. | Net primary production is the rate at which new biomass is generated, mainly due to photosynthesis.
|
| 6. | Therefore, nutrient reabsorption during senescence presents an opportunity for a plant s future net primary production use.
|
| 7. | Both gross and net primary production are in units of mass per unit area per unit time interval.
|
| 8. | Some net primary production goes toward growth and reproduction of primary producers, while some is consumed by herbivores.
|
| 9. | Net primary production is the fraction of gross production remaining after these loss processes have consumed some of the fixed carbon.
|
| 10. | All wetlands combined contribute "'only ~ 7 % "'of global net primary production, as summarized by this 2009, highly cited, peer-reviewed article.
