Describe what Ecosystem services do mountains provide?

They provide vital goods and services -particularly freshwater - to a significant proportion of humanity. Mountains are key centers of biological and cultural diversity as well important sites of traditional ecological knowledge, and influence the climate at many scales.

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.
