[5] Borlaug is often called "the father of the Green Revolution", [6] [7] and is credited with saving over a billion people worldwide from starvation.
The energy remaining after respiration is considered the net primary production. In general, gross production refers to the energy contained within an organism before respiration and net production the energy after respiration. The terms can be used to describe energy transfer in both autotrophs and heterotrophs.
Net ecosystem production (NEP) in ecology, limnology, and oceanography, is the difference between gross primary production (GPP) and net ecosystem respiration. [1] Net ecosystem production represents all the carbon produced by plants in water through photosynthesis that does not get respired by animals , other heterotrophs , or the plants ...
Can the green shoots of clean energy break through the “brown blockade”?
Such is the scale of food production in the country that in 2017, greenhouses occupied nearly 5,000 hectares. [55] Greenhouses began to be built in the Westland region of the Netherlands in the mid-19th century. The addition of sand to bogs and clay soil created fertile soil for agriculture, and around 1850, grapes were grown in the first ...
