Plants use nitrogen primarily to make proteins and nucleic acids essential for growth and development. This process occurs through nitrogen fixation in specialized bacteria or through absorption of nitrogen compounds in the soil. Excess nitrogen can become stored in the plant as reserves or get released back into the environment through decomposition.
Most plants use single nitrogen atoms, not N2 molecules.
Denitrification bacteria in the soil are beneficial as they help convert nitrates into nitrogen gas, reducing nitrogen pollution. However, in excess, they can result in nitrogen loss from the soil, leading to decreased soil fertility and affecting crop productivity. Farmers need to manage these bacteria to balance nutrient availability in the soil.
Nitrogen needs to be fixed before it is used by plants.
The term for abnormal increase in height due to an excess of growth hormone is gigantism. This condition usually occurs before puberty when the growth plates are still open, resulting in excessive growth of the long bones.

Excess nitrogen in the body can be used for muscle protein synthesis or be converted into urea and excreted by the kidneys as urine. Adequate protein intake and regular exercise help maximize the benefits of excess nitrogen for muscle growth and repair.
One direct outcome of excess nitrogen is eutrophication, a phenomenon where increased levels of nitrogen in bodies of water lead to excessive algal growth. This can deplete oxygen levels in the water, harming aquatic life and ecosystems.
No
Excess nitrogen can lead to eutrophication, where increased nutrient levels in bodies of water stimulate the growth of algae and plankton, leading to oxygen depletion and potentially harming aquatic life.
it ends up in the ocean where it feeds algal blooms
Excess nitrogen in the air can lead to eutrophication of water bodies when it is deposited into bodies of water through rainfall. It can also contribute to air pollution, smog formation, and acid rain, which can have detrimental effects on human health and the environment. Additionally, excess nitrogen can disrupt nutrient balances in ecosystems, leading to changes in plant and animal populations.
Excess lime can increase soil pH, making nitrogen less available to plants. This is because high pH levels can convert nitrogen into ammonia gas, which can then be lost through volatilization. This can reduce the amount of nitrogen available for plants to take up and use for growth.
People put nitrogen in fertilizers because nitrogen in the form of ammonium nitrogen is essential for a plant's growth.
Nitrogen fixation is important for plants because it converts atmospheric nitrogen into a form that plants can use to grow and thrive. Nitrogen is a vital nutrient for plant growth and is a key component of proteins, chlorophyll, and other essential molecules. Without nitrogen fixation, many plants would struggle to obtain enough nitrogen from the soil to support their growth.
An aquatic ecosystem or nearby waterway causes rapid and overabundant growth of algae.
