Which labels best complete the flow chart?
julsineya [31]

Answer:

The labels that best complete the flow chart are:

X: Free nitrogen is in the atmosphere and Y: Producers captivate components of nitrogen via their roots.

Explanation:

Soil comprises nitrogen, it is taken up by the plants accompanied by other minerals in the process of taking water from the soil. The presence of nitrogen in the soil takes place by the process of decomposition of decaying and dead substances. The process of decomposition dissociates nitrogen and discharges it within the soil. This nitrogen is eventually taken up by the plants.  

Label X shows that in the air presence of nitrogen takes place in its free state, as it is one of the gases found in abundance in the atmosphere of the Earth.
