The Canadian elk has traditionally been limited in its geographic range by the presence of elderberries, its primary source of f
ood, which only grow up until a certain point in the tundra. A recent rise in temperatures, however, has seen a spread in the growth of elderberries northwards into the tundra. Therefore, the overall range of the Canadian elk can be expected to increase. Which of the following, if true, best casts doubt on the argument?
A. In addition to elderberry, the Canadian elk also consumes loganberries, which are expected to also begin growing at more northerly latitudes.
B. During the summer months, many Canadian elk are hunted both for sport and for their meat.
C. The grizzly bear, the Canadian elk’s primary predator, has also started moving north into the tundra.
D. The permafrost, the region above the tundra, in which the temperatures never reach above freezing, will unlikely see elderberry growth.
E. Increasing temperatures have created conditions too warm for elderberry growth in the southern half of the Canadian elk’s traditional territory.
E. Increasing temperatures have created conditions too warm for elderberry growth in the southern half of the Canadian elk’s traditional territory.
Explanation:
Increasing temperatures have created conditions too warm for elderberry growth in the southern half of the Canadian elk’s traditional territory, this option best casts doubt on the argument.
The changing ocean currents lead to climate cooling by bringing cooler breezes to places with higher climates. The cool breezes push the warm air out and leads to the drop of temperature
Many desert areas are caused by subtropical high pressures. Such areas are consistently warm, dry and also sunny. And are the Arabian desert in the middle east and in Africa, the Sahara desert. It is also called the horse latitude and have it's latitudes between 30 and 35 degree in the north and south. Rainfall is supposed and winds is variable with calm winds sometimes.
