Higher oxygen levels in the atmosphere will lead to an increased voracity and size in those organisms that utilise oxygen as an energy source. IE. most living creatures on earth.
It is essentially volatile and toxic, however, and so increasing it beyond current levels would be unlikely to be positive.
If current levels of atmospheric Co2 however, were increased 5 fold, then plant life would thrive and be able to live in currently desolate areas such as desert and tundra ensuring an extremly abundant food supply and revitalising the planets ecosystems.
Roses help the environment by creating more oxygen and less carbon dioxide.
well plants provide oxygen, oxygen helps us to live.
they give us food and oxygen .. thats a really good question :)
Well it helps because the oxygen that plants provide help you breath.
due to the present of sunlight photosynthesis is take place and its help to growth plant themselves and help to give oxygen to animals, maintain the oxygen level to environment.
Oxygen is a benefit to the environment..... Dah !
Because the oxygen Is taking out all the pollution in the air and if the was no oxygen the environment would die
An anaerobe is an organism that thrives in an environment without oxygen. Facultative anaerobes prefer an oxygen-free environment but can survive in the presence of oxygen. Obligate anaerobes are destroyed by oxygen and cannot survive if it is present in their environment.
the evolution of cellular respiration, which used oxygen to help harvest energy from organic molecules
UMM... well, plants & animals take in carbon dioxide(oxygen) and then they release it for fresher air i guess.
Frogs eat flies and bad bugs so we wont get sting by bees and other stuff. Frogs help by farting oxygen so we have more oxygen to breathe
Lung and gills help animals take in oxygen from their environment. Lungs are found in terrestrial animals and allow for the exchange of oxygen and carbon dioxide during respiration, while gills are found in aquatic animals and perform a similar function by extracting oxygen from water.
