Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.
2. What is the carbon cycle?
Mar 2, 2023 · When humans burn these fuels for energy, vast amounts of carbon dioxide are released back into the atmosphere. This excess carbon dioxide ...
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change. Where the carbon is located — in the atmosphere or on Earth — is constantly in flux.

FAQs
Based On The Diagram Above, Which Of The Following Processes Reduces The Amount Of Carbon Dioxide In The Atmosphere? Responses Photosynthesis Photosynthesis Cellular Respiration Cellular Respiration Decomposition Decomposition Burning Of Fossil Fuels? ›
Based on the diagram above, which of the following processes reduces the amount of carbon dioxide in the atmosphere? A: Photosynthesis (During photosynthesis, primary producers use carbon dioxide in the atmosphere as the carbon source to produce organic carbon compounds.)
Which of the following processes reduces the amount of carbon dioxide? ›Photosynthesis removes CO2 from the atmosphere and replaces it with O2.
What process indirectly removes carbon from Earth's atmosphere? ›Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis. The ocean is another example of a carbon sink, absorbing a large amount of carbon dioxide from the atmosphere.
Which of the following major storage reservoirs of carbon stored in the form of carbon dioxide? ›The primary reservoirs of carbon dioxide are the oceans, the terrestrial surface (primarily in plants and soil), and geological reserves of fossil fuels.
Which of the following best explains why decomposers in soils and water are important to ecosystems? ›Which of the following best explains why decomposers in soils and water are important to ecosystems? They recycle nutrients.
What reduces carbon dioxide in photosynthesis? ›Reductants produced by linear electron transfer in the thylakoid membrane are mainly used to reduce carbon dioxide and dioxygen in the chloroplasts.
What is carbon dioxide reduced to during photosynthesis? ›During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Which of the processes that remove carbon from the atmosphere is the fastest? ›Which processes remove carbon from the atmosphere? Which of these processes is the fastest? - Photosynthesis & diffusion from the atmosphere to the oceans remove carbon from the atmosphere. - Photosynthesis by algae (phytoplankton) is faster.
How do plants remove carbon dioxide from the atmosphere? ›Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
What releases carbon dioxide into the atmosphere? ›Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.
Which of the following reduces the amount of carbon in the atmosphere? ›
1) Trees and Forests
Plants remove carbon dioxide from the air naturally, and trees are especially good at storing CO2 removed from the atmosphere by photosynthesis.
Carbon moves in the biotic reservoir via food chain. Carbon returns to the abiotic reservoir via respiration, death, excretion. Weathering, combustion, uplifting, etc., return carbon trapped in rock/petroleum to return to the atmosphere.
What are the four 4 main storage reservoirs for carbon on Earth and how they store carbon? ›Most of Earth's carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles. Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
What is the process by which a soil nutrient is reduced and released to the atmosphere as a gas? ›Denitrification. Denitrification is the biological process in which nitrate is converted to atmospheric N2. It is one source of N loss from the soil.
Why are decomposers an important part of all environments explain where they would be placed in a food web? ›they can be absorbed by the producers (e.g. plants and algae) of the food cycle. Decomposers provide the essential nutrients that are required for the survival of 'producers' in the food chain. Though decomposer occupies the lowermost position in the food web, they are the most critical component of the food web.
What are the most important or active decomposer organisms in the soil? ›They are known as decomposers. By far the most important microscopic decomposers are bacteria, which do the lion's share of decomposition in the compost heap. But there are other microscopic creatures such as actinomycetes, fungi, and protozoa, that also play an important role.
What is the only process in the diagram will take carbon out of the atmosphere? ›Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals.
What are the two main ways carbon is recycled? ›Photosynthesis and respiration are actually reciprocal to one another with regard to the cycling of carbon: photosynthesis removes carbon dioxide from the atmosphere and respiration returns it (Figure 5.3. 4). A significant disruption of one process can therefore affect the amount of carbon dioxide in the atmosphere.
