Why are the volcanoes important to the plants on earth?
Question Date: 2011-02-24
Answer 1:

Volcanos are the main source of carbon dioxide in the Earth's atmosphere. Plants ordinarily take this carbon dioxide and use energy from sunlight to build it into sugars, which they then use to live off of as well as make up their bodies. Without volcanos, there would be no carbon dioxide, no plants, and no life on Earth.
