So the scenario is there are two fish species, species one and species two, that live in the same lake at the same time, and are competing for the same prey, which of the following is or are a possible outcome of that competition.
00:15
And again, you're allowed to select all that apply.
00:18
So in the first scenario, species one is better at obtaining prey than species two and drives species two to extinction in the habitat.
00:27
That is certainly possible if the competition is strong.
00:35
So if species one is such a better competitor that it takes up the majority of the prey so that species two doesn't get enough to maintain itself or to where the birth rate would outpace the death rate, then certainly species two would, populations would decline and could ultimately end in extinction.
00:59
So if that is possible, then the second scenario where species two is better at obtaining prey than species one, and then species one, one is driven to extinction that is certainly also possible, right? but again, it would have to be very strong competition.
01:17
Not knowing the strength of the competitive interaction or the sort of the resource base, it's hard to tell, but those would both be possible.
01:25
The third is species one begins to forage for prey in the shallow portions of the lake.
01:29
What species two forages in the deeper parts of the lake and both species persist...
