Question

sydney drew a flow chart to illustrate the nitrogen cycle.which labels best complete the flow chart?x: producers undergo photosynthesis.y: nitrogen compounds are released into the air.x: nitrogen compounds are released into the air.y: producers undergo photosynthesis.x: free nitrogen is in the atmosphere.y: producers absorb nitrogen compounds through their roots.x: producers absorb nitrogen compounds through their roots.y: free nitrogen is in the atmosphere.bacteria fix nitrogen from the air.consumers eat other organisms.decomposers break down dead organisms.

Explanation:

• In the nitrogen cycle, free nitrogen (\(N_2\)) is initially in the atmosphere (\(X\)).
• Bacteria fix this atmospheric nitrogen into forms (like nitrates) that producers (plants) can absorb through their roots (\(Y\)).
• Consumers eat producers (and other consumers), and decomposers break down dead organisms, but the cycle starts with atmospheric nitrogen and then plant absorption after fixation.

Answer:

X: Free nitrogen is in the atmosphere. Y: Producers absorb nitrogen compounds through their roots.
