Natural Selection

A group of similar organisms that do produce fertile offspring (offspring that can reproduce)

• Species

• Population

• Generation

When species produce more offspring than can survive, this is called

• Overproduction

• Competition

• Predation (predator/prey)

When resources are limited , organisms compete for these resources (food, land), and this is called...

In this forest environment, why do the green moths survive?

• Their predators don't like the color green

• They fly faster than the brown moths

• Their coloring makes them better adapted to the environment
