text: There are four main factors influencing photosynthesis and several corollary factors. The four main are:
  * Light irradiance and wavelength
  * Water absorption
  * Carbon dioxide concentration
  * Temperature.
  Total photosynthesis is limited by a range of environmental factors. These include the amount of light available, the amount of leaf area a plant has to capture light (shading by other plants is a major limitation of photosynthesis), the rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of water, and the availability of suitable temperatures for carrying out photosynthesis.
