The graph shows a trend in an ecosystem over time caused by increased pollution in the region. what can you conclude from the graph? a. there’s lower biodiversity among birds. b. there’s a higher reproductive rate among birds. c. there’s a significant decline in the number of producers. d. other types of animals were unaffected by pollution.

The correct answer is - A. There's lower biodiversity among birds.

The pollution in the region obviously had a devastating effect on the bird's population and the bird species. According to the graph, in a very short period of time, the decline in the biodiversity among the bird species is very dramatic, where from around 1,700 bird species, in little more than five years, the number of species dropped little more than 200 species.

It can be concluded that the majority of the bird species in the region had been heavily affected by the pollution, and they were very fragile and vulnerable to the changes in their environment, which resulted in their extermination. The rest of the bird species that manged to survive are for sure more opportunistic in their diets and highly adaptable species, but if the pollution continues they will face the same as the rest.

There’s lower biodiversity among birds.

if im not wrong, i believe you just $7 on the first year, and then 10% of 77 as so on
