Rising levels of carbon dioxide most likely have a greater detrimental effect on the land than the sea. have a greater detrimental effect on the sea than the land. can increase productivity on the land and the sea. can decrease productivity on the land and the sea.

The answer is;  can decrease productivity on the land and the sea.

When there is increased carbon dioxide in the atmosphere,  more carbon dioxide Is dissolved by the seas. This increases the pH levels of the water of the sea. Increase in pH causes coral bleaching  and hence decreases biodiversity in this ecosystem.

Also, on land, global warming (caused by greenhouse gases such as carbon dioxide) causes climate change. Climate change reduces the biodiversity of crops on land and hence reduces productivity including disadvantaging farmers that depend on farming for income.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
