Rosa drew a flow chart of the carbon cycle.

Flow chart of the carbon cycle with 4 boxes connected by arrows. Box 1: carbon dioxide in the atmosphere. Box 2: X. Box 3: consumers eat producers. Box 4: Y. The arrow that follows box 4 connects to box 1.
Which labels best complete the flow chart?
A
X: Producers undergo photosynthesis.
Y: Decomposers return carbon to the soil and release waste.
B
X: Decomposers return carbon to the soil and release waste.
Y: Producers undergo photosynthesis.
C
X: Decomposers take in carbon dioxide.
Y: Producers absorb carbon through their roots.
D
X: Producers absorb carbon through their roots.
Y: Decomposers take in carbon dioxide.

Answers

The correct Answer is A.

The Flow chart of the Carbon Cycle, will look as follows:

1. Carbon dioxide in the atmosphere.

2. Producers undergo photosynthesis (in this process plants among other producers like algae, use CO2 to produce energy).

3. Consumers eat producers (a primary level of consumer like a rabbit eats the producers or plants).

4. Decomposers return Carbon to the soil and release waste.

And the  cycle continues again, by going back to step 1.

The answer would be A! :)

The figure of speech is hyperbole and through it, the reader can infer that Seabiscuit is a very fast horse.

What is a hyperbola?

A hyperbole is a figure of speech that allows a term within the text to be emphasized through exaggeration. In the text above, we can see that the narrator claims that Seabiscuit is the fastest horse in the universe.

This is an exaggeration, since there are no horses in the entire universe, nor would it be possible to determine which is the fastest. However, this exaggeration serves to show the reader how fast Seabiscuit is, despite its physical structure.In the text above, we can see that the narrator claims that Seabiscuit is the fastest horse in the universe.

Therefore, The figure of speech is hyperbole and through it, the reader can infer that Seabiscuit is a very fast horse.
