Carbon is a very important element in biology. what are some of the reasons that organisms need carbon?

1- Carbon is an essential element for living beings, since it is part of the structure of organic molecules.

2- Carbon dioxide is used for some organisms to perform photosynthesis.

3- Carbon dioxide is a greenhouse gas.

4- Carbon is found in living things, the atmosphere, aquatic environments, soil and rocks.

5- The carbon cycle involves the geological cycle and the biological cycle.

6- Among the processes carried out by living beings, which are essential for the carbon cycle, are photosynthesis, respiration and decomposition.

7- The greenhouse effect is fundamental for the development of life on the planet.

8 - Global warming is an accentuation of the greenhouse effect. This warming is related to melting glaciers, rising sea levels, species extinction, among other problems.

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
