Describe Nitrogen Cycle-Nitrogen cycle in simple terms

[Music] welcome to Mumu Math and Science in this video I'd like to talk about the nitrogen cycle our atmosphere is made up of 78% nitrogen we need the nitrogen for our DNA and for proteins but we just can't breathe in the nitrogen Like Oxygen but we must absorb our nitrogen in our food nitrogen follows a cycle where it travels from the atmosphere to the soil to animal and back and inate cycle nitrogen in the atmosphere falls to the Earth by precipitation such as rain or snow once in the soil it finds its way to bacteria

on the root of of plants at the roots the nitrogen is combined with hydrogen to make ammonia in a process called nitrogen fixation lightning in the atmosphere can also do this now ammonia is toxic so additional bacteria combines this ammonia with oxygen in a process called nitrogen ification at this point the nitrogen is is in a form called nitrite additional nitrifying bacteria convert this nitrite to nitrate at this point plants can absorb this nitrogen in a process called assimilation however not all of the nitrate is absorbed but some of it goes to the bacteria that

release the nitrogen to the atmosphere in a process called denitrifying the nitrogen returns to the atmosphere also once in the animal after it eats the plants the animal either dies or needs to get rid of waste another type of bacteria then takes this and along with decomposers and breaks this nitrogen either in the waist or the dead animal and by a process called ammonification the nitrogen can enter the cycle once again at nitrification and the cycle continues I hope that helps with the nitrogen cycle which is how nitrogen keeps recycling itself and remember Mumu math
