Adaptations, Natural Selection, & Artificial Selection LS4.3.4.5

Front

What are variations in a species?

Back

Variations are the differences among individuals of the same species, such as different bird beaks.

Front

What is another term for Natural Selection?

Back

Survival of the fittest.

Front

How does the food supply affect bird beak adaptations?

Back

Changes in food supply can lead to changes in genetic traits, such as beak shape, that improve survival.

Front

What is the role of predators in natural selection?

Back

Predators can influence which traits are favorable for survival, as they tend to prey on individuals with less advantageous traits.

Front

What is an adaptation?

Back

An adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

How do environmental changes impact species?

Back

Environmental changes can lead to shifts in available resources, prompting species to adapt or face extinction.

Front

What is the significance of genetic traits in natural selection?

Back

Genetic traits determine how well an organism can survive and reproduce in its environment.

Front

What happens to a population when a new predator is introduced?

Back

The population may decline if individuals with less favorable traits are more likely to be preyed upon.

Front

How do light and dark mice populations change in response to predation?

Back

If hawks can see light mice more easily, the light mice population may decrease while the dark mice population may increase.

Front

What is the impact of competition on natural selection?

Back

Competition for resources can lead to natural selection, favoring individuals with traits that allow them to compete more effectively.
