Nitrogen Cycle Quiz

What is nitrogen fixation?

• The process of converting nitrogen into oxygen.

• The process of converting oxygen into nitrogen.

• The process of converting carbon dioxide into nitrogen.

• Conversion of nitrogen gas into a usable form

Which organisms are responsible for nitrogen fixation?

• Fungi and algae

• Plants and animals

• Viruses and protists

• Bacteria and archaea

What is the process of nitrification?

• The process of nitrification involves the conversion of ammonia to nitrate and then to nitrite by bacteria.

• The process of nitrification involves the conversion of nitrate to nitrite and then to ammonia by bacteria.

What is the significance of the nitrogen cycle?

• It helps in the production of oxygen.

• It helps in the decomposition of organic matter.

• It helps in the recycling of nitrogen, which is essential for plant and animal life.

• It helps in the production of carbon dioxide.

How does the nitrogen cycle contribute to the growth of plants?

• The nitrogen cycle provides plants with essential nitrogen nutrients.

• The nitrogen cycle improves water absorption.

• The nitrogen cycle increases the pH level of the soil.

• The nitrogen cycle helps plants absorb carbon dioxide for photosynthesis.
