Why does the presence of invasive species generally result in a decrease in biodiversity of native species in an area?

a.) invasive species are invasive because they release toxic compounds into the environment, killing native species.

b.) invasive species lack natural predators and quickly outcompete natives for food and shelter.

c.) invasive species naturally thrive in low biodiversity habitats because even their native habitat is low biodiversity.

d.) the only way to get rid of invasive species is to use pesticides, which kills both invasive and native species.

I believe the answer would be B, Invasive species lack natural predators and quickly outcompete natives for food and shelter.

B.) Invasive species lack natural predators and quickly outcompete natives for food and shelter.

Explanation:

An invasive species is the one which is introduced either accidentally or intentionally is capable of competing the members of the native species for resources like food, shelter, mates and other needs. The introduction of such species is responsible for the decrease in abundance, distribution and migration of the native species. As these species are new to the region there exists no possible predator which can limit the growth of such species.

On the basis of the above description, B.) Invasive species lack natural predators and quickly outcompete natives for food and shelter. is the correct option.
