I would say D. not all endangered species are able to propagate themselves in captivity.
<span>It's a proposition which states that the two species competing for the same resources cannot coexist if other ecological factors are constant. When one species has even the slightest advantage. One of them will always overcome the other one which will eventually lead to extinction of the other one.
Hope this helped!!</span>
D) Blue Jays and Finches nest in the same Oak Trees.
Explanation:
This is an example of competition because two species are for the same thing, in this case, oak trees to nest in.
Okay so if you divide 4 with 3 you will get 55 so the answer should be 70
Ecological systems often remain in balance if only one factor is altered.
