Plants lose water meanwhile carbon dioxide enters plant leaves through stomata, the small pores on the leaf surface. The release

The capture and release of carbon dioxide (CO2) by the forest is the net result of many biological processes. The

In the Northern Hemisphere, the CO2 rises in the winter and declines in the summer, mainly as a response to the

The water holding capacity of air depends sharply on the air’s temperature (i.e. the warmer the air is, the more

The diurnal and annual cycle in solar radiation is reflected into air temperature by the absorption of solar radiation. The

Gases enter and leave the leaf through stomata, which actively control the gas exchange of CO2 and H2O, for example, between

Years of measurements have produced a lot of information on plant respiration. We know more or less how the respiration

We measure the shoot respiration by the same measurement setup as photosynthesis. Trunk respiration needs a special measurement chamber. Root

Plant needs energy for growth, transport and maintenance of vital functions as animals do. To get the energy required, they

The carbon used for ecosystem growth (net primary production, NPP) is eventually transferred to the soil in litter fall, root
