Comparing adaptations
What organ in a plant is most similar in function to the skeleton of a human?
stem or trunk
When the environment changes, an organism can either adapt, die, or ___________________.
move to a new location
What if an environmental change happens too quickly for organisms to reproduce and adapt?
They must either move to a new location or die.
What organ of a human is most similar in function to the bark of a tree?
skin
Imagine there has been a terrible forest fire. Which of the following organisms is LEAST likely to survive?
a. owl
b. bear
c. frog
d. grass
d. grass
What if an environmental change happens very very slowly over time? What will the organisms in that environment do?
They will most likely adapt instead of moving or dying.
What function do the bright colors of a peacock and the bright colors of a flower serve?
Which type of animal is BEST adapted to live in a cold climate?

Were the dinosaurs able to adapt or move to a new location when the asteroid hit the Earth 65 million years ago?
No. The change was too catastrophic. They all died.
A tortoise has a hard shell. A bean seed has a hard coating. What function do these both serve?
protection
Two species of gecko live in a rainforest. The species are very similar in adaptations. Their main difference is that species A reproduces once per year, while species B reproduces twice per year. After one hundred years, which species is most likely to have survived?
Species B, because it produced more offspring, increasing its chances of having a variety of traits and therefore survival.
At the end of the last ice age, saber toothed tigers died off more quickly than woolly mammoths. What can you infer?
The woolly mammoths were slightly better adapted to the changing environment, allowing them to survive for longer.
What organ on a plant is MOST similar in function to the stomach of a human?
the leaves
How are plants able to "move" to a new location?
Seed dispersal. The parent plant doesn't move, but their offspring will grow in a new location.
Which is better: To have a species where all the members are exactly the same, or to have a species where the members have a variety of traits?
Having a species where the members have a variety of traits, because it increases the liklihood of survival if the environment changes.
