The Nitrogen Cycle

James, Daniel, and Mia are studying the nitrogen cycle. They want to know the process that moves nitrogen from the air to the soil. What is this process called?

• Assimilation

• Nitrification

• Denitrification

• Nitrogen fixation

Abigail, Isla, and Liam are working on a biology project. They need to identify a molecule that does NOT require nitrogen. Which of the following molecules should they choose for their project?

• DNA

• RNA

• Proteins

• Glucose

Michael, Ava, and Mia are working on a science project about the Earth's atmosphere. They are debating about the main component of our atmosphere. Can you help them identify it?

• Oxygen

• Carbon dioxide

• Nitrogen

• Hydrogen

Evelyn, Sophia, and Avery are working on a science project about bacteria. They came across a type of bacteria that can break the triple bond of nitrogen gas. Can you help them identify the name of this bacteria?

• Assimilating bacteria

• Nitrifying bacteria

• Denitrifying bacteria

• Nitrogen fixing bacteria

Ava, David, and Liam are studying the nitrogen cycle in their biology class. They learned about different ways nitrogen moves through food webs. David is particularly interested in how animals get nitrogen. How does nitrogen move through food webs in this context?

• Through assimilation

• Through nitrification

• Through denitrification

• Through consumption

Harper and Anika were working on their science project about the nitrogen cycle. They learned about a process that converts nitrates back into nitrogen gas. Can you help Evelyn identify what this process is called?

• Assimilation

• Nitrification

• Denitrification

• Nitrogen fixation

• In waterlogged soils

• In dry soils

• In sandy soils

After James' pet fish died, he buried it in his backyard. What happens to the nitrogen in the fish's body as it decomposes?

• It becomes ammonia again

• It becomes nitrates

• It becomes denitrified

• It becomes nitrogen gas
