What are the consequences of increased nitrogen deposition over terrestrial or aquatic ecosystems?

Nitrogen is one of the major abundant gas in the atmosphere occupying 78% by volume.

It plays an important role in controlling the aquatic and terrestrial ecosystem. The presence of high amount of nitrogen in the atmosphere can lead to the release of large amount of pollutants that includes ammonia and ozone, which can cause difficulty in breathing, visibility problems and at the same time, it will also the affect the growth and expansion of plants. It also can damages to the forests, soils, and water.

The presence of extremely large amount of nitrogen gas in the aquatic ecosystem can also influence the growth of aquatic plants and algae. When these organisms are present in a large number then it blocks the water in-taking path of these plants. It eventually consumes the dissolved oxygen as soon as they decompose, as a result of which it does not allow the light to penetrate into the deeper water (zones).

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

fe 55.85 g/mol and h2o 18.02 g/mol.
