Question

which of the following does not release carbon back into the atmosphere MEDAL!
a.volcanic eruption
b.respiration
c. burning fossil fuels
d. photosynthesis

Answer 1

What do you think it should be?

Answer 2

.volcanic eruption

Answer 3

Nopes, volcanic eruption releases a good amount of carbon dioxide, carbon monoxide etc and thus releases back carbon into atmosphere.

There is one process among the given options which actually uses carbon-dioxide and releases back oxygen to the atmosphere and that is the corrrect answer.

Answer 4

B. or c. not sure which though

Answer 5

You are just guessing and not thinking :(

Does burning fossil fuels produces carbon-dioxide?
Do you take in oxygen and breath out carbon-dioxide to perform respiration?

Answer 6

yes they all seem to produce carbon-dioxide thats why i asked for for help

Answer 7

Yes, if they produce carbon-dioxide, it means they release carbon back into the atmosphere. All these processes namely, volcanic eruption, respiration and Burning of fossil fuels produce carbon-dioxide and thus releases back carbon into the atmosphere. The only left option is photosynthesis.

Photosynthesis is a process by which green plants synthesize glucose. During this process they `take in carbon-dioxide` and `release oxygen back to the atmosphere.`
