The carbon source of nature
Between heaven and earth, the source of carbon dioxide, many natural phenomena are contained in it.

Volcanic eruption, its momentum is majestic. Flames soar into the sky, lava overflows, and at this time, the carbon dioxide hidden deep in the earth, with the hot magma, spews out and disperses into the atmosphere. Like the wrath of the earth, it exhales heavy breath, adding this thing to the atmosphere.

The realm of the forest is also related. The forest leaves are lush, photosynthetic, absorbing carbon dioxide and breathing oxygen, which is the phenomenon of daytime. At night, everything in the forest breathes, and animals and plants breathe out carbon dioxide to return to the atmosphere. And when the forest fire starts, the flames burn the forest, the grass and trees turn into ashes, and the carbon element in between also quickly turns into carbon dioxide and rises in the air.

Oceans, the wide area of water, is also a huge reservoir of carbon dioxide. Sea air is connected, and carbon dioxide is exchanged at the sea surface. Water temperatures are different, and the trend of exchange is also different. Above warm water, carbon dioxide tends to escape into the atmosphere; where cold water absorbs more of this gas. And the metabolism of marine organisms, shellfish, algae, etc., also contributes to the transformation and flow of carbon dioxide in seawater during the cycle of life and death.

Under the soil, microorganisms are active. It decomposes organic matter, such as fallen leaves, residual roots, etc. During this process, carbon elements are gradually transformed into carbon dioxide through microbial action, which slowly rises into the atmosphere from soil pores.

All these are the sources of carbon dioxide in nature, intertwined with each other, and co-evolved in the world.
