Biodiversity is a necessity to sustain life on Earth‚ each species playing an important role in the various cycles which maintain and sustain life on the planet. Without one species another species who depends on it could go extinct or over-populate without the other to control it‚ causing a domino effect that disrupts the balance of life as a whole and the overall biodiversity of this planet. The Alligator Snapping Turtle is one of those various species which helps to promote life and maintain a
