What is the role of volcanoes in the Earth's system?

Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations. The internal heat associated with young volcanic systems has been harnessed to produce geothermal energy

Explanation:

Volcanoes play a role in how Earth looks today. Thanks to NASA's missions, we know more about volcanoes in our solar system. Studying volcanoes can teach us about the interior properties of the planets and moons.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
