What is the role of respiration in keeping the levels of oxygen and carbon dioxide steady?
it uses up oxygen and produces carbon dioxide
1 of 6
What is the role of combustion(burning) in keeping the levels of oxygen and carbon dioxide steady?
It uses oxygen and produces co2. It has less effect on oxygen levels,bc much more oxygen than co2 in the atmosphere
2 of 6
What is the role of photosynthesis in keeping the levels of oxygen +co2 steady
it uses up co2 and produces oxygen, the effects of photosynthesis and respiration approximately balance each other
3 of 6
What is their a debate on?
Global warming
4 of 6
What do many scientists blame to be the cause of global warming?
the increase in co2 in the atmosphere caused by the burning off fossil fuels
5 of 6
Consequences of global warming
rising temps-could cause polar ice caps to melt,flooding low level land. Weather patterns-could be disrupted-more extreme weather conditions,changes in climate,living things not survive in changed habitats
