Question

What is photosynthesis? Write the amount of CO2 in ocean and atmosphere?

Answer 1

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Of the three places where carbon is stored—atmosphere, oceans, and land biosphere—approximately 93 percent of the CO 2 is found in the oceans. The atmosphere, at about 750 petagrams of carbon (a petagram [Pg] is 10 15 grams), has the smallest amount of carbon.

Answer 2

• process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water
