Which of the following elements is deposited into aquatic and terrestrial ecosystems when used in intensive agricultural practices?

Nitrogen from heavy fertiliser use is deposited into aquatic and terrestrial ecosystems in intensive agriculture.

Phosphorus also runs off from farms, but nitrogen is the element most widely deposited across both ecosystem types here.

Sulphur is tied more to fossil-fuel burning and acid rain than to intensive farming inputs.

With a definite element identified, the claim that none applies is ruled out.

Excess nitrogen leaches into groundwater and washes into rivers and lakes.

It drives eutrophication and disturbs the natural nitrogen balance.
