Which activity would be best keep the worlds oxygen supply from decreasing?

Planting more trees and preserving existing forests is the best way to maintain the world's oxygen supply. Trees absorb carbon dioxide and release oxygen through photosynthesis, helping to balance the oxygen and carbon dioxide levels in the atmosphere. By protecting and expanding forest areas, we can help mitigate the decrease in the world's oxygen supply.


What is the oxygen supply on the moon?

The moon has a very thin atmosphere with no oxygen. Therefore, there is no natural oxygen supply on the moon. Humans would need to bring their own oxygen supply if they were to visit or live on the moon.


Why is oxygen a common reactant?

There is a large supply of oxygen in Earth's natural atmosphere, and oxygen is a strongly electronegative element.

How does the light reaction of photosynthesis affect the earths supply of oxygen?

Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.


What effect does photosynthesis have on the amount of oxygen in the atmosphere?

Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.


Why does a space shuttle carry its own supply of oxygen?

A space shuttle carries its own supply of oxygen to sustain the astronauts' breathing when they are in space where there is no atmosphere. It ensures they have a continuous source of oxygen for respiration during the mission.


What produces oxygen in the forest?

Trees, plants, and other photosynthetic organisms in the forest produce oxygen through the process of photosynthesis. During photosynthesis, these organisms use sunlight, carbon dioxide, and water to produce oxygen and carbohydrates. This oxygen is then released into the atmosphere as a byproduct of this process.


What is the biggest contributor to the earths oxygen supply?

The biggest contributor to Earth's oxygen supply is phytoplankton. These microscopic marine plants generate over half of the oxygen in our atmosphere through photosynthesis. Forests and other plants also play a significant role in oxygen production.


Why did god made nitrogen more aboundant than oxygen in the atmosphere?

Because Nitrogen makes plants grow and they provide a continuous supply of oxygen!


Why do spacecraft need internal oxygen supply?

Spacecraft need an internal oxygen supply to provide a breathable atmosphere for astronauts during space travel. Since there is no oxygen in space, spacecraft must carry their own supply to support human life. This ensures that astronauts have the necessary oxygen to breathe and carry out their activities while in space.


How much oxygen does a rain forest create?

A rainforest can generate about 20% of the world's oxygen production due to the vast number of trees and plants that undergo photosynthesis. However, this oxygen is mostly consumed by the forest itself and its surrounding ecosystem, rather than being released into the atmosphere.
