nitrogen cycle

Nitrogen cycle

Important in structure of DNA and proteins

Stored in oceans likes marshes and soil

Nitrogen fixation

Process that makes this nitrogen available to plants

Nitrogen cycle through interactions between living and nonliving things

Nitrification

Occurs when certain nitrifying bacteria converts Ammonium to nitrate

Nitrate enters plant roots through the process of uptake

Herbivores then eat plant and use nitrogen

denitrification

Nitrates are converted back to N2 by the notifying bacteria

Nitrogen cycling

Volcano eruptions

Nitrogen dissolves in water enters, waterways and washes into lakes and oceans, and settle and settle settlements

Nitrogen, trapped in rocks

Human influences in the nitrogen cycle

Using fertilizer

Algae Bloom uses all CO2 and O2 and block sunlight killing many aquatic organisms

Burning fossil fuels

Clearing forests and burning releases, trapped, nitrogen into atmosphere, which increases acid precipitation

Overgrowth of algae

Algae bloom

Rain carries nitrogen from farms, gardens, and lawns into aquatic ecosystems

Algae and plants at the water surfaces grow quickly this block sunlight from reaching deeper water

Deeper water plants get no sunlight they cannot carry out photosynthesis so they no longer give oxygen and then soon starve to die

When the plants die decomposers have lots of food, the number of decomposers increases quickly they use this as the oxygen in the water as they carry out cellular respiration

As oxygen in the water is used up aquatic organisms that need oxygen suffocate and die
