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.
Is called autotroph organisms that create organic molecules needed for survival from inorganic sources. this is achieved through photosynthesis (which is light energy) or chemosynthesis (which is chemical energy).
And photosynthesis is when autotrophs capture and convert the light energy from the sun into usable chemical energy (which is their food).
i just answered the same question like 20 min ago XD
Using a molecular clock, scientists are able to estimate the amount of time that two species have been evolving independently.
Hope this helps :)
