Answer 1

Hi there! :)

Answer:

Glaciers.

Step-by-step explanation:

Forest fires, Volcanoes and the use of fossil fuels all are sites of combustion. Carbon dioxide, or
`CO_(2)` is a byproduct of this reaction, which makes them sources of this gas.

On the other hand, glaciers are large, frozen reservoirs of water
`(H_(2)O)` , which makes them not sources of carbon dioxide.
