Why does darkness affect the light-independent reactions of photosynthesis?

plants stop their daytime activities and rest during the night much like animals do.

light independent reactions need more heat energy than nighttime temperatures often provide.

mitochondria produce sugars more effectively in the darkness than chloroplasts do.

light independent reactions require the energy gathered in the thylakoids.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
