Question

at a nature preserve in northern california biologist recorded twenty species of native arts within a community these species resided apart from each other and maintained a healthy balance among the populations when nonnative argentine ants moved into the area this balance changed dramatically

Answer 1

The ants, probably were subctracting fundamental resources to the previous population simply destroying the habitat.
