In 1955, conservationists in Hawaii were concerned about an invasive species, the giant African land snail, Achatina fulica. A. fulica was reproducing widely and had few predators. In an attempt to control the invader and protect the environment, the conservationists imported the rosy wolf snail, Euglandina rosea (E. rosea), that preys on other snails for food. Which of the following explains what will most likely happen to A. fulica? Why? E. rosea quickly becomes the top predator, instead of A. fulica. The number of A. fulica decreases. A. fulica and E. rosea become competitors, but A. fulica remains the top predator. The number of A. fulica stays constant. A sudden genetic mutation in A. fulica causes them to become smaller and more attractive to E. rosea. The number of A. fulica decreases. Natural selection causes A. fulica to grow bigger, be more aggressive, and eat more snails, including E. rosea, over time. The number of A. fulica increases.

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
