How many hours of sleep will i get if i fall asleep now?

It does depend on when you wake up. For example if you go to bed at 8pm and wake up at 6am then that will get you with 10 hours of sleep

every el niño cycle is different. every year.

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.
