CO2
Most water vapor enters the atmosphere through processes like evaporation from bodies of water, transpiration from plants, and sublimation from ice and snow. These processes convert liquid water to water vapor, which then rises into the atmosphere and contributes to the water cycle.
The atmosphere
The process by which water vapor enters the atmosphere during the water cycle is called evaporation. In this process, water from bodies of water, such as oceans, lakes, and rivers, is heated by the sun and changes into water vapor, which rises into the atmosphere.
Approximately 505,000 cubic kilometers of water enters the hydrologic cycle annually.
The process is called the water cycle. It involves evaporation of water from oceans and other water bodies, condensation into clouds, precipitation as rain or snow, and runoff that eventually returns water back to the oceans or enters groundwater. This continuous cycle ensures water circulates from the atmosphere to the Earth and back.
The phosphorus cycle does not involve a stage where a chemical enters the atmosphere. Phosphorus mainly cycles through the lithosphere, hydrosphere, and biosphere, with minimal direct involvement of the atmosphere.
The source of carbon for the Calvin cycle is carbon dioxide.
Roughly 84% of the water in the water cycle enters the atmosphere through evaporation from the Earth's surface such as oceans, rivers, and lakes.
CO2
The Calvin cycle is a carbon dioxide gas from the atmosphere and the energy carried by ATP and NADPH to make simple sugars.
The reactant in the Calvin cycle is carbon dioxide (CO2) from the atmosphere. This carbon dioxide is fixed and converted into organic molecules, such as glucose, through a series of enzymatic reactions in the Calvin cycle.
NADPH and ATP from the light reactions enter the Calvin cycle aka the dark reactions
the calvin cycle
In the Calvin cycle, a leaf takes in carbon dioxide (CO2) from the atmosphere and gives off oxygen (O2) as a byproduct of photosynthesis.
The chloroplast is the organelle that participates in the Calvin cycle. Within the chloroplast, the stroma is where the Calvin cycle takes place.
When acetyl CoA and oxaloacetate is present.
The Calvin cycle is a part of photosynthesis where carbon dioxide from the atmosphere is converted into glucose, a carbon-based molecule. This glucose, along with other carbohydrates produced in the Calvin cycle, serves as the main energy source for plants. When you eat plants or plant-based foods, you consume these carbon-based molecules, which are then used by your body for energy and building blocks in cellular processes.
