Question

What change is likely to occur in a population of beetles that suddenly faces predation from an invasive species of frogs? A. The beetles' survivorship curve will change type. B. The beetles' minimal viable population will decrease. C. The carrying capacity of beetles will increase. D. The population density of beetles will decrease.

Answer 1

It depends on the type of beetles being attacked. There are poisonous and non-poisonous beetles. If a group of frog attacks a population of poisonous beetles and eat them up, there is a 100% chance they are going to vomit it out  because a poisonous beetle explodes a poisonous secretion in frog's stomach which causes an irritation hence frog vomits it out.

Unlike a normal scenario, beetles play predator here whereas frogs irregardless to their size become the prey.

Answer 2

population density of beetles will decrease
