How does irrigation affect ecosystem health?

Reduced river flow.

Increased groundwater recharge, waterlogging, soil salinity.

Reduced downstream river water quality.

Affected downstream water users.

Lost land use opportunities.

Groundwater mining with wells, land subsidence.

Case studies.

Reduced downstream drainage and groundwater quality.

Explanation:

maybe because its impossible for balloons to lift a whole entire house.

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.
