There have been centrists in both sides of politics, who serve alongside the various factions within the Liberal and Labor parties. In addition, there are a number of smaller groups that have formed in response to the bipartisan system who uphold centrist ideals.
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.
The biosynthesis of organic compounds in chemosynthesis is achieved by autotrophic assimilation of CO 2 (Calvin carbon reduction cycle) just as in photosynthesis. Energy is obtained in the form of ATP from electron transfer via the chain of respiratory enzymes incorporated into the bacterial cell membrane.
