Question

Pet owners begin to abandon their Burmese pythons in the Everglades when they become too large for home care. Native species of frogs and reptiles decrease with the introduction of the snakes. What does this scenario represent?
a. a loss of biodiversity due to an invasive species
b. a loss of biodiversity due to a catastrophic event
c. a loss in biodiversity due to mutualism
d. a loss of biodiversity due to a commensalism

Answer 1

You've been told that the number of native species decreases, so you have a loss of biodiversity. The question asks you to look at the cause. Burmese pythons are obviously not native to the 'Glades so they should be classified as an invasive species.
