In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy.

Carbon :

coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose.

Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen

Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans.

Hence, Photosynthesis removes CO2 from the atmosphere and replaces it with O2.

From the given circuit,

The resistors R1 and R2 are in parallel connection and R3 is in series with R1 & R2

The equivalent resistance of R1 and R2 is

Req = (12 × 4)/(12 + 4) = 3 Ω.

Adding R3 in series with the pair gives

R = Req + 9

R = 3 + 9

R = 12 Ω.

The process accounts for species diversity is Meiosis. Meiosis is termed as a specialized cell division which reduces chromosomes number by half and then creates for haploid cells.
