Answer:
The proportion of oxygen went up because of photosynthesis by plants. The proportion of carbon dioxide went down because: it was locked up in sedimentary rocks (such as limestone) and in fossil fuels. it was absorbed by plants for photosynthesis.
Explanation:
Answer:
The carbon and water cycle I know, but I can't help with the nitrogen cycle. Sorry.
Explanation:
Carbon cycle - The role that plants play in the carbon cycle is that they take in our carbon dioxide and put out oxygen, which we breathe. So we give the plant air and they give us air.
Water cycle - The role that plants play in the water cycle is when it rains, the plants absorb some of the water in their roots, thus making them strong and therefore helping the ground not become a mud hole.
Sorry that I can't help with the nitrogen cycle. But I hope what I was able to help you with helps!
Answer:
Aerobic cell respiration is roughly 18 times more efficient than anaerobic cell respiration. Your cells require a lot of energy and are dependent on the high efficiency of aerobic respiration. Overall, aerobic respiration converts about 40% of the available energy of glucose into ATP.
When the temperature of the air becomes almost equal to the dew point the air becomes saturated and the relative humidity during this condition becomes 100%. If the temperature of the air decrease below the dew point the relative humidity will be 100% or exceeds 100%. This condition, when the temperature of the air decreases below the dew point is called supersaturation but most of the time the temperature of the air will be lower than the dew point.
Answer:
i had to list all the facts cuz we didnt have a diagram
Explanation:
The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
