What chemical property of nitrogen makes it suitable for producing chemicals safely and for food packaging?
Nitrogen has the property of being inert, meaning it does not react with many other chemicals. This makes it ideal for use in creating chemicals safely and in food packaging because it helps prevent reactions that can spoil or degrade the product. Nitrogen also helps to extend shelf life by displacing oxygen, which can lead to oxidation.
How does nitrogen enter a food web?
Nitrogen enters a food web through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can absorb. Plants then take up this nitrogen through their roots, and it is passed through the food web as animals consume plants and other animals. When organisms die and decompose, nitrogen is released back into the soil for plants to utilize again.
How do plants get nitrogen compared to how animals get nitrogen?
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
How do plants get atmospheric nitrogen?
some plants have bacteria in their roots which contain nitrogen when plants want nitrogen they exchange their food made them with nitrogen. Example: pea plants contain bacteria called rhizobium which contains nitrogen
Why food is stored in a refrigerator?
Food is stored in a refrigerator to slow down the growth of bacteria and other pathogens that can lead to spoilage and foodborne illness. The cold temperature of the refrigerator helps to keep food fresh for longer periods of time by inhibiting microbial activity. Refrigeration also helps to maintain the quality, texture, and flavor of the food.
How does a refrigerator keep food fresh?
Because it keeps food cold.
Why is nitrogen used in crisp packets?
Nitrogen is used in crisp packets due to its inert properties, which help maintain the freshness and crispiness of the chips. By replacing oxygen with nitrogen, the oxidation process that degrades the chips is slowed down, allowing them to stay fresh for longer periods.

Why do they use nitrogen in food packaging?
Nitrogen gas is used in food packaging because it helps to displace oxygen, which can cause food spoilage due to oxidation. By replacing the oxygen with nitrogen, the shelf life of the food is extended as it reduces the growth of bacteria and slows down degradation. Additionally, nitrogen is an inert gas and does not react with the food product, helping to maintain its quality and freshness.
Why is a refrigerator so important?
It keeps food fresh and cool...this means the activity of the bacteria is slowed down.
What is nitrogen used for for kids?
Nitrogen is used to make the air we breathe and to help plants grow. It is also used to make fertilizer for plants, and in some cases, to freeze food to keep it fresh.
Why will the fridge help to keep the food fresh?
The cold temperature helps slow microbial and enzymatic activity in food which keeps it fresher longer than storing it at higher temperatures.
What gas is used in packet foods to keep the contents fresh?
nitrogen that works as antioxidant and prevent rancidity
