Which term best describes the change from more light-colored moths to more dark-colored moths?
competition
evolution
acquired
overpopulation

Answer 1

When it comes to biology, these terms mean different and specific things that happen during the lifespan of a species.

Competition occurs when different species or even organisms fight against each other to take control of their particular habitat. These species or organisms can compete with one another for food, water, or just to claim their territories.

Evolution is when a species develops something to benefit them as time progresses and the world changes.

When something is acquired, that means the species got it, but was not born with it. A virus can be a perfect example of this!

Lastly, adaptation is when an animal changes itself to better survive its environment. An example of this can be when an animal gets a thicker coat for the cold winter, or changes color to blend in with its environment.
