The present level of atmospheric carbon dioxide is approximately 380 parts per million and rising rapidly due to human activities such as burning fossil fuels, deforestation and cement manufacture. Until the beginning of the Industrial Age, the long term average concentration of carbon dioxide was in the range 260 to 280 ppm, falling to around 160 ppm during cold periods, but never as high as the present level during all human history.

How does this process feeding in carbon dioxide affect or control atmospheric CO2?
The process of feeding in carbon dioxide, such as through photosynthesis in plants, plays a crucial role in regulating atmospheric CO2 levels. During photosynthesis, plants absorb CO2 from the atmosphere and convert it into glucose, effectively reducing the concentration of CO2 in the air. This natural process helps mitigate climate change by acting as a carbon sink, thus balancing the carbon cycle. Additionally, when carbon is stored in biomass and soils, it further controls CO2 levels by sequestering carbon for long periods.
What process of the carbon cycle is likely causing the increase in carbon dioxide levels in carbon dioxide levels?
The increase in carbon dioxide levels is primarily caused by the process of combustion, where fossil fuels such as coal, oil, and natural gas are burned for energy. This releases stored carbon into the atmosphere in the form of CO2. Additionally, deforestation contributes to rising CO2 levels by reducing the number of trees that can absorb carbon dioxide through photosynthesis. These human activities significantly enhance the natural carbon cycle, leading to higher atmospheric carbon dioxide concentrations.
What is the dominate atmospheric gas on mars?
The dominant atmospheric gas on Mars is carbon dioxide (CO2), making up about 95% of the planet's atmosphere.
What specific factors make atmospheric carbon dioxide levels decrease?
Atmospheric carbon dioxide levels decrease primarily due to photosynthesis, where plants absorb CO2 to produce oxygen and glucose. Oceanic absorption also plays a crucial role, as oceans take up significant amounts of CO2 from the atmosphere. Additionally, geological processes such as the weathering of rocks and the formation of carbonates can sequester carbon over long timescales. Lastly, human activities that reduce fossil fuel combustion and promote renewable energy sources contribute to lower atmospheric CO2 levels.
What are two ways that the burning of rainforests leads to an increase in atmospheric carbon dioxide?
The burning of rainforests releases carbon dioxide (CO2) into the atmosphere, as the combustion of anything does.When the rainforests are destroyed they no longer are able to remove CO2 from the atmosphere.Both these things lead to an increase in atmospheric carbon dioxide.
What evidence indicates that the rising atmospheric carbon dioxide levels are caused by the combustion of fossil fuels?
the average global temp and the atmospheric co2 level has risen
Why do atmospheric carbon dioxide concentrations fluctuate seasonally?
Atmospheric carbon dioxide concentrations fluctuate seasonally due to the natural processes of photosynthesis and respiration in plants. During the growing season, plants take in carbon dioxide for photosynthesis, which reduces the amount of CO2 in the atmosphere. In the winter, when plants are dormant, there is less photosynthesis and more respiration, leading to an increase in atmospheric CO2 levels.
What is the c source for autotroph?
Atmospheric carbon dioxide (CO2).
Why arent atmospheric levels of carbon dioxide rising as rapidly as might be expected based on the increase output of carbon dioxide resulting from human activities?
Atmospheric levels of carbon dioxide (CO2) are not rising as rapidly as expected due to several factors, including the natural absorption of CO2 by oceans and terrestrial ecosystems, which act as significant carbon sinks. Additionally, changes in land use, reforestation efforts, and improvements in agricultural practices can enhance carbon uptake. Climate variability and human-induced changes in land management also play a role in regulating CO2 levels. Lastly, the efficiency of human activities in emitting CO2 can vary, affecting overall atmospheric concentrations.

How are ancient CO2 levels measured and what methods are used to determine the historical atmospheric carbon dioxide concentrations?
Ancient CO2 levels are measured by analyzing air bubbles trapped in ice cores from glaciers and ice sheets. Scientists also study the chemical composition of fossilized plant material and marine sediments to determine historical atmospheric carbon dioxide concentrations.
Why are atmospheric carbon dioxide levels significantly lower in summer than in winter in a deciduous forest?
During the summer, deciduous trees undergo photosynthesis where they take in carbon dioxide to produce energy. This process helps to lower the atmospheric carbon dioxide levels. In winter, when the trees are dormant and not actively photosynthesizing, there is less carbon dioxide being absorbed, leading to higher levels in the atmosphere.

How do you spell carbondiocide?
The correct spelling is carbon dioxide, an important atmospheric compound (CO2).
