Answer:
The right answer to this question is option B. The optimum habitat for the golden-cheeked warbler population is a 100 juniper trees per acre
Step-by-step explanation:
When you look at the other alternatives, all of them don't make sense with the information the graph shows, let's take a look at them one by one. The first one says that once the juniper trees per acre increases, the population of golden-cheeked warbler does it aswell, but that's not true once that graph shows that, after a 100 trees, the population decreases.
The third one says that the population stabilizes when there are more than a 120 juniper trees, that's not true, because the population starts to decrease after this. And the last one mentions that golden-cheeked warblers cannot survive once there are juniper trees on the environment, of course this is not true just by the graph information where it shows some warblers when these trees are aroung.
