<span>Both photoautotrophs and chemoautotrophs synthesize organic compounds from (inorganic) carbon dioxide, a process known as carbon fixation. Photoautotrophs get the energy to perform these reactions from light. Chemoautotrophs get it from electron donors such as hydrogen sulfide and ammonia. Cyanobacteria, by contrast, convert nitrogen from the atmosphere into ammonia, a process known as nitrogen fixation.</span>
<span>The ocean affects the earth’s climate by utilizing the sun’s
energy. Based on the amount of the Sun’s
energy that is absorbed by the ocean, multiple things can happen. For example in
California, the sun heats the Pacific Ocean which heats the winds, which brings
the warm climate to the state. Also, the ocean’s play a major role in the water
cycle. The amount of precipitation falling on an area can affect its weather
and climate. hope this helps!!!! </span>
