What phenomenon on Earth lowers the amount of CO2 in our atmosphere?

Question

need help please

Answer 1

photosynthesis uses CO2 to make sugar and oxygen

Answer 2

The reason that we have such a high level of oxygen in our atmosphere is because of plants. They photosynthesize, and use carbon dioxide and water to make food (sugar). Their waste product is oxygen. Specifically, there is excess oxygen because of the many plants that died but did not release their CO2 - they formed the fossil fuels. Therefore, when these fuels are burned, they release the CO2. Knowing this, I think you can answer the question... encourage more plants, and use less fossil fuel!

Answer 3

All green plants photosynthesize and break co2 into o2 and sugars the plants use. If you look at co2 graphs, as deciduous trees leaf, co2 levels drop. This is only temporary though and co2 is re-released as the tree is oxydized through various processes.

Answer 4

Rain or snow wash CO2 out of the atmosphere by dissolving it . At current levels of CO2, the rain or snow has a pH of 5.6, indicating the relative acidity of CO2 to that of water.

Answer 5

Solubility of CO2 in the sea.
The Greenies would want an answer like trees absorb CO2 but this gets released when the tree dies or is burnt etc.

Answer 6

Plants do some of the work but they also respire at roughly the same rate as they engage in photosynthesis. I believe it's something like 90% of the photosynthesis that really makes a difference comes from the oceans, mainly from corals and algae, seaweed and the like.

Answer 7

Plant respiration. Plants utilize CO2 and produce O2

Answer 8

hydrogen helps lower the CO2 in our atmosphere.

Answer 9

plants use co2 for photosynthesis, but the levels are actually rising for many reasons like the burning of fossil fuels

Answer 10

Trees
