How does fertilizer running into a pond lower the oxygen level?

The fertilizer causes an increase in algae. As algae die and are decomposed the decomposers increase and use up all of the oxygen in the water.


What is the Level of oxygen on Saturn?

There is oxygen in the atmosphere of Saturn, but it is only a tiny fraction of the deep atmosphere, which is mostly hydrogen. It is not in a usable form as is oxygen on Earth.


Is there oxyen on Mars?

There is a very small amount of oxygen on Mars. The oxygen level in Marsâ?? atmosphere said to be around .145%.


It is said that by planting more trees will help in increase oxygen level but even they give out carbondioxide during night time so the quetion is why not the carbondioxide level increases by planting?

During the day, trees perform photosynthesis and produce oxygen while absorbing carbon dioxide. At night, they undergo respiration and release some carbon dioxide but in much smaller amounts compared to the oxygen produced during the day. Overall, the net effect of planting trees is an increase in oxygen levels and a decrease in carbon dioxide levels in the atmosphere.


What happens when higher energy UV radiations act on the oxygen at the higher level of the atmosphere?

ozone layer prevents harmful UV radiations to reach earth's atmosphere. ozone is formed at the higher level of atmosphere by the action of UV radiation on molecule. High energy UV radiations split apart some oxygen molecules into atomic oxygen which react with molecular oxygen to form ozone molecules.

What causes an increaSE in oxygen level?

An increase in oxygen level can be caused by processes such as photosynthesis in plants, diffusion of oxygen into water from the atmosphere, or release of oxygen during chemical reactions. Human activities may also contribute to an increase in oxygen levels by reducing pollution or planting trees that produce oxygen.


How do you increase oxygen level in atmosphere?

don't smoke, excercise, espessially walking.

Why does the nitrogen level in the atmosphere is higher than the oxygen level?

Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.


An oxygen deficient atmosphere has an oxygen concentration less than?

An oxygen deficient atmosphere has an oxygen concentration less than the normal level of around 21%.

Why does earths atmosphere today contain more oxygen then the early earth?

The increase in oxygen in Earth's atmosphere is mainly due to the evolution of photosynthetic organisms like cyanobacteria and plants, which produce oxygen as a byproduct. Over time, these organisms gradually increased oxygen levels through the process of photosynthesis. This led to the rise of oxygen in the atmosphere from less than 1% to the current level of around 21%.


How did the evolution of photosynthetic prokaryotes affect the level of oxygen in the atmosphere?

Photosynthesizing prokaryotes affected the ancient atmosphere by adding oxygen. In ancient times the oxygen level was .42%, compared to the 21% oxygen level now. Photosynthesizing prokaryotes have made the world livable today.


What is the minimum amount of oxygen needed to sustain fire in the atmosphere?

The minimum amount of oxygen needed to sustain a fire in the atmosphere is about 16% oxygen. Below this level, the fire would not have enough oxygen to continue burning.


How long has the oxygen concentration of the atmosphere been at its current level?

The current oxygen concentration in the Earth's atmosphere has been relatively stable at around 21% for the past 300 million years. This level is maintained through processes like photosynthesis by plants and phytoplankton, which convert carbon dioxide into oxygen.


Does the troposphere have oxygen?

Oh yes. The troposphere is the lowest level of the atmosphere, the level that we live and breathe in, and it does have lots of oxygen in it, until you get to very high altitudes.


Where in atmosphere does meteoroids burn?

"where the oxygen level increases then combustion takes place"
