Question

rosa drew a flow chart of the carbon cycle. which labels best complete the flow chart? co₂ is in the atmosphere. x: producers undergo photosynthesis. y: decomposers return carbon to the soil and release waste. x: decomposers return carbon to the soil and release waste. y: producers undergo photosynthesis. x: decomposers take in carbon dioxide. y: producers absorb carbon through their roots. x: producers absorb carbon through their roots. y: decomposers take in carbon dioxide. consumers eat producers.

Explanation:

In the carbon cycle, producers (like plants) take in \(CO_2\) from the atmosphere and perform photosynthesis (so X is producers undergoing photosynthesis). Consumers eat producers. When organisms die, decomposers break them down. Decomposers return carbon to the soil (as organic matter) and release waste (such as \(CO_2\) through respiration), which is why Y is decomposers returning carbon to the soil and releasing waste. Other options are incorrect: decomposers don't take in \(CO_2\) in the way described in some options, and producers mainly take in \(CO_2\) through leaves (not roots for \(CO_2\) uptake - roots absorb water and minerals).

Answer:

X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
