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?

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.

The answer is B. This is because the graph shows the highest number of green parrots in the 'deep forest' category of environment, whereas the numbers in the 'grassland' and 'scrub forest' are less. Since the forested area in Brazil has decreased rapidly, this means that the preferred environment of the green parrot has decreased, probably resulting in a decline in the green parrot population

 B)  There are probably less green parrots today than there once were.

There are probably less green parrots today than there once were. With a change in environmental conditions, the parrot populations change.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
