Answer:
Breathing – It is the physical process, through which all living organisms, including plants, animals and humans inhale oxygen from the outside environment into the cells of an organism and exhale carbon dioxide back into the atmosphere.
Decomposition: It is one of the natural and most important processes in the oxygen cycle and occurs when an organism dies. The dead animal or plants decay into the ground, and the organic matter along with the carbon, oxygen, water and other components are returned into the soil and air. This process is carried out by the invertebrates, including fungi, bacteria and some insects which are collectively called as the decomposers. The entire process requires oxygen and releases carbon dioxide.
Combustion: It is also one of the most important processes which occur when any of the organic materials, including fossil fuels, plastics and wood, are burned in the presence of oxygen and releases carbon dioxide into the atmosphere.
Rusting: This process also requires oxygen. It is the formation of oxides which is also called oxidation. In this process, metals like iron or alloy rust when they are exposed to moisture and oxygen for an extended period of time and new compounds of oxides are formed by the combination of oxygen with the metal.
Explanation: The Stages
Stage-1: All green plants during the process of photosynthesis, release oxygen back into the atmosphere as a by-product.
Stage-2: All aerobic organisms use free oxygen for respiration.
Stage-3: Animals exhale Carbon dioxide back into the atmosphere which is again used by the plants during photosynthesis. Now oxygen is balanced within the atmosphere.

Answer:
The Niger River will be heavily exploited in the future so that it helps the economies in people in the region.
Explanation:
Most of the big rivers around the world are heavily exploited. They have huge dams built on them for multiple purposes, canals that connect places that don't come out on the rivers, transportation, and travel are well organized and on a high scale. The Niger River though is not that exploited despite having huge potential, but that will change in the near future for sure.
This river goes a long way in the interior of Western Africa and the outskirts of Central Africa. It can support boats, and it is the major factor that supports agriculture. Considering that this part of the world is in a dire situation but develops quickly, the Niger River will be used for sure. Huge dams will be made, and the water will be used for the production of electric power to feed the economies, but also for irrigation as the region is mostly semi-arid, for drinking, and for the industry. In order to boost the economy and help in the development of the large urban areas, canals will be made to the ones that are not located at the river's banks. Transportation through the river's waters will skyrocket as it will be fast, safe, and cheap.
Explanation:
Given the importance of oxygen for animals, researchers suspected that a sudden increase in the gas to near-modern levels in the ocean could have spurred the Cambrian explosion. ... This supported the idea of oxygen as a key trigger for the evolutionary explosion.
