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 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.
How are nitrates changed back into nitrogen?
Nitrates can be changed back into nitrogen through a process called denitrification. This process is carried out by denitrifying bacteria in the soil, which convert nitrates into nitrogen gas under anaerobic conditions. This nitrogen gas is then released back into the atmosphere.
Which gas is changed into a useful form for the plants by the bacteria in the soil?
Nitrogen gas is changed into a useful form for plants by nitrogen-fixing bacteria in the soil. These bacteria convert nitrogen gas into a form that plants can absorb and use to grow, known as ammonium or nitrate.
Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances b?
Nitrogen is changed into ammonia by nitrogen-fixing bacteria in soil and water. This ammonia can then be further converted into nitrites and nitrates by other species of bacteria in a process called nitrification. These nitrates are then used by plants to make proteins and other essential molecules.
Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances before being used by living things?
Nitrogen is changed into ammonia and nitrates through the process of nitrogen fixation before being used by living things. This conversion is typically carried out by specialized bacteria in the soil or water.
How has society and environment have changed by use of fertilizers containing nitrogen?
The use of nitrogen-containing fertilizers has led to increased crop yields, which has helped to feed a growing global population. However, overuse of nitrogen fertilizers can lead to water and air pollution, as excess nitrogen can runoff into waterways and contribute to greenhouse gas emissions. Sustainable farming practices and proper fertilizer management are essential to minimize the negative impacts of nitrogen fertilizers on society and the environment.
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.

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).
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.
What process has changed the percentages of nitrogen in the atmosphere?
Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration.
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.
