Answer:
When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapor. Most of the matter in the candle ends up as these two gases.

Answer:
<u>B</u> What role do animals have in the carbon cycle?
Group of answer choices
use water and release oxygen
<u>use sugar and release carbon</u>
use carbon and release oxygen
use carbon and release nitrogen
<u>D, E</u> Select TWO statements that describe what the scientists will observe in the ecosystem after fossil fuels have been extracted and burned.
Group of answer choices
There is more available space for carbon to become fossil fuels.
There is less carbon in storage.
There will be less carbon in the water.
<u>There is more carbon in the atmosphere.</u>
<u>There will be more carbon respired by organisms.</u>
There will be less carbon released through decomposition.
Explanation:
Animals obtain energy through sugar from the food they eat and release carbon into the air through respiration. Therefore, they partake in the carbon cycle by using sugar and releasing energy.
As far as the second question, when fossil fuels are burned, the carbon contained within them is released into the atmosphere in the form of carbon dioxide. So, there will obviously be a greater amount in the atmosphere.
I would like to apologise in advance if either of my option choices were incorrect.
