Question

In what ways is n2 gas removed from the atmosphere?

Answer 1

N2 gas is removed from the atmosphere through denitrification and human activities such as agricultural practices and the combustion of fossil fuels.

Step-by-step explanation:

N2 gas is removed from the atmosphere through several processes, including denitrification and human activities such as agricultural practices and the combustion of fossil fuels. Denitrification is a process in which denitrifying bacteria convert nitrates and nitrites into nitrogen gas, replenishing the atmosphere. Human activities, especially agricultural practices and the use of artificial fertilizers, contribute to the release of nitrogen compounds into the environment, which can lead to excess nitrogen in ecosystems.

Answer 2

One way of removing nitrogen gas from the atmosphere is by natural nitrogen fixation. This is done by nitrogen-fixing bacteria in the oceans and in the soil. Nitrogen fixation is a process that converts the nitrogen in air to ammonia.
