Plants, particularly through the process of photosynthesis, are the primary organisms responsible for absorbing carbon dioxide from the atmosphere. Trees, shrubs, and grasses take in CO2 and convert it into organic matter while releasing oxygen. Additionally, phytoplankton in oceans play a crucial role in carbon absorption, as they account for a significant portion of global photosynthesis. Some microorganisms in soil and oceans also contribute to carbon cycling and storage.
Carbon is returned to the atmosphere through processes like respiration by living organisms, decomposition of organic matter, and combustion of fossil fuels. When organisms respire, they release carbon dioxide back into the atmosphere. Decomposition of dead organic matter also releases carbon dioxide, while burning fossil fuels releases carbon that has been stored underground back into the atmosphere.
Organisms that release carbon from the atmosphere primarily include animals and decomposers. Animals exhale carbon dioxide during respiration, while decomposers, such as bacteria and fungi, break down organic matter, releasing carbon back into the atmosphere. Additionally, combustion processes, including those from humans and natural wildfires, also contribute to carbon release. Overall, these processes play a crucial role in the carbon cycle.
Oxygen in the atmosphere primarily comes from photosynthesis by plants and other photosynthetic organisms. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Over millions of years, this process has led to the accumulation of oxygen in the Earth's atmosphere.
Carbon is returned to the atmosphere through several processes, including respiration, combustion, and decomposition. During respiration, living organisms release carbon dioxide as they break down glucose for energy. Combustion of fossil fuels and biomass also releases stored carbon into the atmosphere as CO2. Additionally, the decomposition of organic matter by microbes and other decomposers releases carbon back into the atmosphere.
Carbon enters the atmosphere primarily through the combustion of fossil fuels, such as coal, oil, and natural gas, which releases carbon dioxide (CO2) as a byproduct. Additionally, deforestation contributes to carbon emissions, as trees that absorb CO2 are removed, leading to increased atmospheric carbon levels. Lastly, natural processes like volcanic eruptions and respiration from living organisms also release carbon into the atmosphere.
The process responsible for the release of carbon dioxide into the atmosphere in organisms is cellular respiration. During cellular respiration, organisms break down glucose to release energy, which produces carbon dioxide as a byproduct.
This is an example of the carbon cycle, where carbon moves between the atmosphere, oceans, land, and living organisms. When the atmosphere has an excess of carbon dioxide, oceans act as a carbon sink by absorbing some of it, helping to regulate the balance of carbon in the environment. This process is important for maintaining Earth's climate and overall carbon balance.

The ocean plays a crucial role in the carbon cycle by absorbing a significant amount of carbon dioxide from the atmosphere through a process called carbon sequestration. This helps to regulate the levels of carbon dioxide in the atmosphere, reducing the impact of greenhouse gases on the climate. Additionally, marine organisms like phytoplankton play a role in the carbon cycle through photosynthesis and the formation of calcium carbonate shells.
Plants contribute to the Earth's atmosphere by releasing oxygen through the process of photosynthesis. This oxygen is essential for the survival of most living organisms, including humans. Additionally, plants help regulate the levels of carbon dioxide in the atmosphere by absorbing it during photosynthesis.
The ocean is currently acting as a carbon sink, absorbing more carbon dioxide than it releases into the atmosphere.
The amount of Oxygen started to increase as more plants and animals appeared. The plants took in Carbon dioxide and gave out Oxygen. So, overtime the amount of Carbon dioxode (which was high) decreased, and oxygen increased.
The carbon oxygen cycle describes the interplay between carbon dioxide and oxygen in Earth's atmosphere, with plants absorbing carbon dioxide during photosynthesis and releasing oxygen, while animals and other organisms consume oxygen and produce carbon dioxide through respiration.
Carbon moves from living things to the atmosphere through processes such as respiration, decomposition, and combustion. During respiration, organisms release carbon dioxide into the atmosphere. Decomposition of dead organisms also releases carbon dioxide. Combustion of fossil fuels by humans is another significant way carbon is released into the atmosphere.
The primary mechanism that helps carbon cycle from the atmosphere to living organisms is photosynthesis. In this process, plants, algae, and some bacteria absorb carbon dioxide (CO2) from the atmosphere and, using sunlight, convert it into glucose and oxygen. This organic carbon is then passed through the food chain as animals consume plants and other organisms, facilitating the transfer of carbon within ecosystems. Additionally, respiration by living organisms returns some carbon back to the atmosphere as CO2.
When living organisms die, they decompose, releasing carbon into the soil and air. Additionally, during respiration, organisms release carbon dioxide into the atmosphere. Human activities like burning fossil fuels also contribute to the release of carbon dioxide into the atmosphere.
