A bird that preys on moths is introduced to the habitat with moths and trees like the ones shown below.
Rufina [12.5K]

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.

How do global systems interact to affect ecosystems?
miskamm [114]

is a functional unit that results from interactions of abiotic, biotic, and anthropogenic components and are a combination of interacting, interrelating parts that form a unitary whole.  Ecosystems vary in size.  They can be as small as a puddle, or as large as the earth itself.  Basically, any living and non-living things interacting together can be considered an ecosystem.  Within each ecosystem, there are habitats that vary in size.  A habitat is a place where a population lives.  A population is a group of living organisms of the same kind living in the same place at the same time.  Natural ecosystems are made up of abiotic factors such as air, water, rocks, and energy and biotic factors such as plants, animals, and microorganisms.
