Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When an organism dies, the nitrogen in its body
A
can never be reused by other living things.
B
is immediately released into the atmosphere.
C
is released by the action of decomposers.
D
None of the above
Explanation: 

Detailed explanation-1: -A wide range of soil fungi and bacteria, called the decomposers, carry out the ammonification process. The decomposers consume the organic matter, and the nitrogen contained in the dead organism is converted to ammonium ions. The ammonium is then converted to nitrates by the nitrifying bacteria.

Detailed explanation-2: -Decomposition. Decomposers (some free-living bacteria and fungi ) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition nitrogen is released into the soil in the form of ammonium.

Detailed explanation-3: -Decomposers break apart complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium. All of these components are substances that plants need to grow.
