Volcanic eruption and animal respiration.
When the cells of plants and animals break down food to produce energy and when fossil fuels (Such as coal and gasoline) are burned.
Great blooms of oceanic algae, or phytoplankton, take carbon out of the atmosphere during photosynthesis. It is then taken deep into ocean with them when they die. Scientists say that this helped cool the earth during the ice ages by removing carbon dioxide from the atmosphere and storing it at the ocean floor, where it cannot be recycled back into the atmosphere.
photosynthesis, where plants use the carbon in the form of CO2, water and sunlight as a heat source to produce fructose and glucose to feed the plant.
Trees take in carbon dioxide, store the carbon in their trunks and branches, and release oxygen into the atmosphere. This process is called photosynthesis and is done by all growing vegetation.
During spring and summer more plants photosynthesize, removing carbon dioxide from the atmosphere. In fall and winter fewer plants are active, and some even die and decay, which releases carbon dioxide. This is more pronounced in the northern hemisphere which contains the most land mass and therefore the most plant life.

Dead trees rotting in the forest.Carbon dioxide escaping from volcanoes.

carbon dioxide
When the cells of plants and animals break down food to produce energy and when fossil fuels (Such as coal and gasoline) are burned.
Carbon dioxide
Carbon dioxide gas.
Driving vehicles that run on fossil fuel. Burning oil releases carbon dioxide.Using electricity. Most electricity is now generated by burning fossil fuels. This burning emits carbon dioxide.
carbon dioxideCarbon Dioxide
In the atmosphere .
oxygen is added to the atmosphere when plants take in carbon dioxide during cellular respiration
The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere
