Answer 1

In the carbon cycle, two ways that carbon is released into the atmosphere are:

1. Cellular respiration: This process occurs in living organisms, where glucose is broken down with oxygen to produce energy, releasing carbon dioxide (CO2) as a byproduct.

2. Fossil fuel combustion: When fossil fuels such as coal, oil, and natural gas are burned for energy, they release carbon dioxide and other greenhouse gases into the atmosphere.

These processes contribute to the carbon cycle by returning carbon from living organisms and fossil fuels back into the atmosphere.
