The balance between oxygen and carbon dioxide in the Tropical Rainforest
Oxygen is the most abundant element in nature according to its mass.
Part of the rocks of the lithosphere, atmosphere (oxygen and nitrogen are about ninety nine percent of the atmosphere), the hydrosphere (water has two atoms of hydrogen and oxygen), animals (formed also by a large proportion of water) and, of course, plants.
The mass of all living beings are formed in greater proportion of oxygen and carbon. But the difference between animals and plants is that the former are consumers and vegetables are food producers.
This means that animals could only appear on earth after the plants appear.
The difference that explains this is that plants produce biomass through photosynthesis, which is the process by which sunlight provide enough energy to transform carbon dioxide and minerals and water from the soil or atmosphere in carbohydrates, which come to be the raw materials used to living things eat, grow and reproduce.
In the process of photosynthesis free oxygen is released almost entirely goes to air or water (by photosynthesis of aquatic plants).
It has been estimated that 28% of oxygen consumed by living beings on our planet comes from the inter-tropical forests.
The remainder is obviously the rest of the vegetation, wild and cultivated in the world; much more widespread on the surface, though not as productive as the one in the jungles in the tropics; which is where the action of the rays has the highest level.
Most of the oxygen released by plants comes from phytoplankton, ie the existing plant material in the seas to reach the depth where sunlight.
Among the aquatic plants are the largest biomass of naturally occurring algae and some varieties can reach several km in length.
