Answer:
"The American Robin is the largest, most abundant and broadly distributed thrush in North America. The presence of this songster in the backyard setting, together with its loud, musical voice, make it one of the most recognizable birds in North America. Indeed, the American Robin has been described as "America's favorite songbird" (Young 2012)".
Hope this helps :)
I think the answer is most likely be J.
The first (F) one the population of the predator increases hugely while the population of the prey was neutral. And so both population didn’t seem to have any connection. Same goes for H. Graph G doesn’t make sense at all the population of the prey didn’t exist throughout the time in the graph but only exist in one single point of time and then just vanish again so that shouldn’t be the answer either.
In graph J, you can see the correlation between the two populations as the predator goes up and so does the prey.
You can search up on google predator-prey relationship graph to get better understanding.
