Answer:
The black and yellow bird population would begin to starve and would be forced to find alternative food, or die off. This would then send ripples through the food web, causing almost every species to be effected by the grasshoppers being gone.
The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities. He used similar fossils from different continents to back up his theory of continental drift. However, at that time, many scientists that had observed similarities in fossils in places like South America and Africa believed there were similar fossils in different continents because of a land bridge that were formed by two continents.
Many science communities believe that land bridges allowed migration of many different species and even people to one place to another by large bodies of water frozen by low temperature known as ice age.
All except number 2. Hope this helps!

Answer:
Continental drift
Explanation:
Alfred Wagener told about continental drift. He said that continents were a single land mass called Pangaea. They were separated and relocated in the form of different continents. The drifting happens due to the movement of tectonic plates above the magma. As a result, the land mass was broken down into different landforms. These broken parts were carried slowly and form the continents. The continents are now also moving slowly
