Question

Imagine you are exploring the Australian Outback and stumble across two perfectly identical fields separated by a natural barrier. Field 1 is covered by large, grass-eating kangaroos and the other is covered by small, grass-eating wallabies.  Each field has an identical amount of grass as a resource.  There are only enough grass resources on field one to support 100 kangaroos, and only enough grass resources on field two to support 150 wallabies (wallabies are smaller so need less grass).  

You find out that a land developer is going to destroy field one, killing all the kangaroos! You decide to instead bring all 100 kangaroos over to field two and introduce them there.  

Assume that  ?(alpha) = .5 for Kangaroos, and ?(beta) = 1 for wallabies.

With all this information, what do you expect would (eventually) happen in this population given infinite time?

You would expect to see roughly 100 wallabies and 50 kangaroos.

You would expect kangaroos to go extinct and to see 150 wallabies.

You would expect wallabies to go extinct and to see 100 kangaroos.

You would expect to see roughly 25 wallabies and 125 kangaroos.

You would expect one of the two species to eventually go extinct but it isn't possible to predict which without more information.

You would expect one of the two species to eventually go extinct but it isn't possible to predict which without more information.

Explanation / Answer

Option D is correct:

here, the idea is given that kangaroos are more and they have dominant affects on wallabies. So wallabies are going to extinct and kangaroos are becoming dominant.

that is why the option d is correct kangaroos have more effect on wallabies which leads to number reduction of them.
