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.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
