Which human-induced change results in increased competition caused by an initial increase in the number of organisms in a habitat?
a. non-sustainable harvesting
b. nonnative species introduction
c. ozone layer depletion
d. mass extinction

B. non-native species introduction

Explanation:

Introduced species in a habitat is a human induced change. Here, new species are brought from other habitats to a new one. These new species are probably useful for human survival.

When these new species enters the new habitat, they quickly integrate into the ecosystem and the population increases. The biodiversity of such an area shoots up.

As the number of species increases, competition becomes prevalent in the habitat. Native species would begin to struggle harder for the limited resources in the environment.

This kind of relationship can lead to a number of adverse effect on the native population. Some species can get phased out as competition becomes rife.

Some other organisms have to change their feeding habit and evolve to newer and safer methods.

The answer is B
