how do animals get nitrogen?\n○ they break down glucose molecules into nitrogen.\n○ they convert carbon to nitrogen during fixation.\n○ they eat it in plants and other animals.\n○ they breathe it in from the atmosphere.

Answer

Brief Explanations:

  • Glucose has no nitrogen, so first option is wrong.
  • Carbon can't be converted to nitrogen, second option is wrong.
  • Animals can't directly breathe in atmospheric nitrogen (most can't utilize N₂), so fourth option is wrong.
  • Animals get nitrogen by consuming plants/other animals that have nitrogen - containing compounds.

Answer:

C. They eat it in plants and other animals.
