Food Sources
Name all of the food sources used in this lab and why they were important.
What is paperclips, beans, and rubber bands
Name all of the utensils used in this lab and what they represented
What is Spoons, Forks, and Clothespins
What is competition?
the interaction between organisms or species where they strive for the same limited resources like food, water, or territory
If a food source disappeared, what would happen to the birds that relied on it?
They would likely experience a decline in population due to a lack of food and struggle to survive.
Which beak type was the most successful at collecting each food type? Why?
Various Responses
How does competition for resources directly affect which traits become more common in a population?
The animals that get the resources are more likely to survive and reproduce that those that do not. Therefore, those traits are passed along future generations.
Why do some beak types lead to greater survival than others
Better suited for that environment, food source, less competition etc
How might a sudden environmental change (e.x., introduction of a new predator or food source) impact the survival of different beak type
individuals with beak shapes that are best suited to access the new food or evade the new predator are more likely to survive.
How does competition for resources directly affect which traits become more common in a population?
What is Natural Selection
How would this bird population change over multiple generations if one type of food became more or less available?
the bird population would likely evolve to have beak shapes and sizes that are better suited to accessing the now more abundant food source. Those that do not evolve will have a decline in population size .
How does this lab model real-world natural selection?
simulating how different beak shapes affect a bird's ability to acquire food in a specific environment
