Nitrogen is cycled through an ecosystem by both plants and ?(animals).

Decomposers break down dead organisms and their waste products to release
?(ammonia)

in a process called ?(nitrification)

These ?(decomposers) can then be used by plants to make amino acids. The process of converting nitrogen in the atmosphere to ammonia is called ?(nitrification)

This process is carried out by bacteria that live in ?(watery soils)
and in ?(the ground)

Plants can absorb both ?(nitrates) and
?(nitrogen gas) from the soil, but animals cannot. Animals obtain
?(nitrates) by eating plants and other organisms and then digesting the proteins they contain.

  6. Science question, only 1

    What would be the consequence of an ecosystem that had no nitrogen-fixing bacteria? Nitrogen from decomposing animals would never be returned to the soil. Decomposers would not be able to break down the nitrogen present in plants
