What role do bacteria play in the nitrogen cycle?

Back

Bacteria convert nitrogen gas from the atmosphere into a usable form for plants and animals through a process called nitrogen fixation.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.
