Two bird species are competing for the same resources.
00:04
Species a is more successful at capturing their prey than species b.
00:09
So better at hunting than b.
00:18
What is likely to happen over time to the population of these two species? is it going to be a? species a will decline, species b will increase.
00:30
B, species a will increase, species b will decline.
00:33
C, they will both increase, d, they will both stabilize, since they are getting sufficient foods, or they will develop a commensal relationship.
00:44
Let's start by ruling out e.
00:46
A commensal relationship is a relationship where two individuals from different species are interacting over a long period of time.
00:54
One has a benefit, and one is unaffected.
00:58
So, for example, you have mites living on your skin, and eyelashes, and they eat dead skin.
01:05
And they don't affect you, but they're getting food.
01:08
That's a commensal relationship.
01:10
So it's not going to happen...
