question 27 of 34
a non - native species of frog is introduced into a pond. which of the following would be most likely to prevent the non - native species of frog from becoming an invasive species?
a. the non - native frog can tolerate the ponds temperature.
b. a native frog species competes with the non - native frog.
c. there are no other frog species living in the pond.
d. the non - native frog has no predators in the pond.

Explanation:

In an ecosystem, competition from native species can limit the growth and spread of a non - native species. If a native frog species competes with the non - native frog for resources like food and habitat, it can prevent the non - native frog from becoming invasive. Tolerating temperature (A) would aid its survival and potentially make it more invasive. Lack of other frog species (C) and lack of predators (D) would also make it easier for the non - native frog to thrive and become invasive.

Answer:

B. A native frog species competes with the nonnative frog.
