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

Non sustainable

Explanation:

All the ecosystem and ecological cycle in the nature are self-sustaining, balanced and self-regulating. Interference of human activities alters the mechanism of self-regulation and hence disturbs the ecological balance and disrupts the connection in between. When the number of organism in a certain habitat are increased then following can occur –  

a)Over exploitation of food (plants, trees and their produce or small animals) on which this organism depends.  

b)Rise in population of  predators feeding on this organism.

These changes make the system unsustainable

Hence, option A is correct

B) nonnative species introduction
