Invasive species cause more damage than some pollutants. Almost half of the native species in America are endangered because of invasive species. Compared to other threats to biodiversity, invasive introduced species rank second only to habitat destruction, such as forest clearing.
For the pheasant question, it would be the top right graph as this shows an increase, then a further increase in the population of pheasants.
For the population of the world graph, it shows positive exponential growth as it is a large amount of growth within a small time period
