Do we use nitrogen in firtilizer?
Yes, nitrogen is a key component in fertilizers. It is essential for plant growth and is often added to soil to improve crop yield and overall plant health. Nitrogen is a major nutrient required by plants for various metabolic activities and is a crucial element in the production of proteins and chlorophyll.
What process has changed the percentage of nitrogen in the earth's atmosphere?
The process that has changed the percentage of nitrogen in the Earth's atmosphere is biological nitrogen fixation, where certain bacteria convert nitrogen gas into a form that plants can use. This has led to an increase in nitrogen levels over time.
How has nitrogen changed in the earths atmosphere today?
Nitrogen gas makes up about 78% of Earth's atmosphere today. However, human activities have altered the nitrogen cycle by increasing the amount of reactive nitrogen in the environment through processes like fertilizer use and fossil fuel combustion, which can lead to environmental issues like air and water pollution.
Is the ratio nitrogen to oxygen changed by altitude?
Yes, the ratio of nitrogen to oxygen in the atmosphere remains constant regardless of altitude. Both nitrogen and oxygen are main components of Earth's atmosphere, with nitrogen making up about 78% and oxygen about 21%. Other gases, such as trace gases like argon and carbon dioxide, make up the remaining 1%.
What is nitrogen changed into before being used by living things?
Nitrogen is changed into ammonia through a process called nitrogen fixation, typically carried out by soil bacteria or certain plants like legumes. Ammonia is then converted into other forms of nitrogen such as nitrites and nitrates that are taken up by plants for growth and utilized by other living organisms in the food chain.
How society and the environment have been changed by the use of fertilizers containing nitrogen?
The use of fertilizers containing nitrogen has led to increased agricultural productivity and food production, addressing global food security concerns. However, nitrogen runoff from fertilizers can pollute water bodies, leading to harmful algae blooms and ecosystem degradation. It also contributes to air pollution and climate change through the release of nitrous oxide, a potent greenhouse gas.
What is the difference between most fertilizers?
Commercial fertilizers are usually composed of three basic ingredients: Nitrogen, Phosphorus and Potassium. Depending on the plant results a gardener or farmer may wish for, the proportions of these three chemicals are changed.
How have fertilizers changed farming?

What process has changed the percentage of nitrogen in the atmosphere?
Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration.
What are two ways nitrogen from the air changed into usable nitrogen?
lightning & bacterial action (nitrogen fixers).

What is the term for the biological process where by atmospheric nitrogen is changed into a form usable by plant?
Nitrogen fixation.
When nitrogen is fixed it is changed into?
When nitrogen is fixed, it is changed into ammonia, which can then be used by plants to make proteins and other essential compounds. This process is mainly carried out by nitrogen-fixing bacteria in the soil or by industrial processes.
Which nutrient is changed by bacteria into different forms?
Nitrogen is a nutrient that is changed by bacteria into different forms through a process called nitrogen fixation. Bacteria can convert atmospheric nitrogen (N2) into forms that plants can use, such as ammonium (NH4+) or nitrate (NO3-). This process is important for bringing nitrogen into the ecosystem and making it available for plant growth.
