I believe the answer is: The dark colored moths will experience disruptive selection
The bird prey on moth and possibly identify the moth by visual sense. The moth has two type of color: dark and light. The trees in the area is more light coloured so the black moth will be identified easier as their color is more contrast to the tree. As the dark moth easier to identify, they will be predated more and their population will be reduced. When a trait has advantage than the other, disruptive selection happens.
For the first one I’d say D
The answer for the 2nd one is C.
Answer:
commensalism
Explanation:
One organism is benefited while the other is not harmed or benefited.
Answer:
α = 0 if β= 0
Explanation:
If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.
So it could fit perfectly.
