There is a relationship between light, primary production, and ecological energy budgets. Sunlight is the primary input of energy into the planet's ecosystems. Light is composed of electromagnetic energyof different wavelengths. Radiant energy from the sun generates heat, provides photons of light measured as active energy in the chemical reactions of life, and also acts as a catalyst for genetic mutation.[2][86][157] Plants, algae, and some bacteria absorb light and assimilate the energy throughphotosynthesis. Organisms capable of assimilating energy by photosynthesis or through inorganic fixation of H2S are autotrophs. Autotrophs--responsible for primary production--assimilate light energy that becomes metabolically stored as potential energy in the form of biochemical enthalpicbonds.[2][86][157] 47.
