Answer:
Explanation:
Last year we had the most handsome of ducks -- a mallard. He was with us until the end of June at which time the water on our property dried up. I have a feeling his mate got tired of sitting on the nest all the time and demanded he help. They built their nest in a thicket that was impossible to get near. We knew about where it was, but it did us no good.
We did get to see the young ones once or twice. It is amazing how quickly they grow. By the end of September, they were all ready to go south -- even the young ones.
This year is very dry -- there's no water for them. So we have not seen the mallards or ducks of any kind and no geese either. We all miss them.
The following which would best categorize Canada's population is concentrated in the south. The three big cities are actually all within under a five-hour distance from the border of the United States (Montreal, Toronto and Vancouver). Cities in Canada are often concentrated in the southern part, because the further north you go, the colder it gets and the cold can often be quite brutal in Northern Canada.
I personally believe that the right answer is C. Other overpopulation results in more living organisms, and since the pollution has intoxicated the living, they die releasing the carbon into the soil. So there is high amounts of carbon and less of the organic compounds because the overdose on carbon.
