According to fossil records and recent published observations, two species of leaf-eating beetles (species A and B) have existed on an isolated island in the Pacific Ocean for over 100,000 years. In 1964 a third species of leaf-eating beetle (species C) was accidentally introduced on the island. The population size of each species has been regularly monitored as shown in the graph above.

a) Propose an explanation for the pattern of population density observed in species C.

b) Describe the effect that the introduction of beetle species C has had on the population density observed in species A and B

c) Predict the population density of species C in 2014. Provide a biological explanation for your prediction.

d) Explain why invasive species are often successful in colonizing new habitats.

a) species C is an invasive species. it has seized species' B's food source and outbred it.

b) species A appears to have a separate niche/food source and remains unaffected. B however appears overwhelmed by C's population expansion and suffers.

c) 30-whatever increment it says. the ecosystem may not be able to support any more than that. the species may simply crash all together and die out.

d) they fuck like rabbits.

To elaborate on D, more reasons could be that they lack a natural predator in a new ecosystem, or that they compete aggressively for resources.
