The graph above was made by a south american biologist in the country of brazil, after a long study on parrots. about 200 years ago, 90% of brazil was covered in mature, deep forest. today, well over half of this forest has been cut to make way for farms. what conclusion could you draw about the parrots in the graph?
a) red parrots have become less common in the last 200 years.
b) there are probably less green parrots today than there once were. c) blue parrots probably are the best adapted species to live on farms. d) the blue parrot population has likely increased in the last 200 years.
