Rosa drew a flow chart of the carbon cycle.Which labels best complete the flow chart?







A. X: Decomposers take in carbon dioxide.
Y: Producers absorb carbon through their roots.

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

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

D. X: Producers absorb carbon through their roots.
Y: Decomposers take in carbon dioxide.

Answer 1

The correct answer is Option B

The Block X in the figure shows that the producers utilized the carbon dioxide present in the environment and produced food by the process of photosynthesis.

Then the consumers feed on the producers and used the food prepared by the producers.

The Block Y in the figure shows that when the consumers died, the decomposers came into action and decomposed the body of the consumers and returned the carbon back into the atmosphere.

Answer 2

The right answer is B

A primary producer corresponds, in an ecosystem, to an autotrophic living being, that is to say capable of producing organic matter from mineral matter. It is the first element of the food chain. This organism is totally or partially ingested by a primary consumer, itself being the potential target of secondary consumers.

Decomposers are living creatures that contribute to the degradation of dead organic matter or feces by returning them in mineral form. They play a crucial role in an ecosystem because they participate in the recycling of the elements.
