In which of the following spheres of earth does diffusion of carbon dioxide from the hydrosphere occur? . atmosphere. biosphere. cryosphere. geosphere

Atmosphere

Explanation:

The carbon dioxide is a colorless gas. It is composed of one carbon atom and two oxygen atoms. It is present naturally in the earth atmosphere but the concentration of carbon dioxide can increase by the human activities like burning of fossil fuels, and deforestation. The hydrosphere is one of the sphere of the earth which includes the water bodies. The carbon dioxide being a gas present in the atmosphere can diffuse inside a water body (ocean, river, lakes) which is the part of hydrosphere.

answer: c

explanation:

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
