Question

Which human-induced change results in increased competition caused by an initial increase in the number of organisms in a habitat?

non-sustainable harvesting
nonnative species introduction
ozone layer depletion
mass extinction

Answer 1

The human-induced change that results in increased competition due to an initial increase in the number of organisms in a habitat is **nonnative species introduction**. When nonnative species are introduced into a new habitat, they can proliferate quickly, often outcompeting native species for resources such as food and habitat, thereby increasing competition within the ecosystem.
