Al of these will be the consequences except C, increase in polar ice. The rise in temperature is already causing the polar ice to melt down. The further increase in temperature will make the situation of the polar ice worse. the rise in vegetation in Tundra and Tyga regions could be seen because they are very cold areas and temperature increase may help vegetations to survive.
Answer:American Goldfinch follows this pattern. Beginning in September, and continuing for six to eight weeks, they molt all of their feathers, ending up with a completely new and pristine set of feathers (and drab colors) as they head into the winter. In the spring, as they grow new body feathers the males especially transform into bright yellow breeding plumage, but the wing and tail feathers remain from the previous fall. As these wing feathers get older the pale buff edges fade to white and disintegrate, so that by the end of the summer the wings look essentially all black. And in September another complete molt begins.

Ecological system can affect one another regardless of how small or great the factor that was altered. This can have gradual and insidious effects on the ecosystem. <span>Ecosystem is
encompassing all the life on earth in the physical environment that
supports it. An ecosystem involves both the biological (plants, animals,

things are very dependent on the abiotic community since it cannot
survive by itself.</span>
