What is Natural Selection?
An animal's ability to survive based on genetic/physical traits it has inherited
100
True or False:
An ecosystem is a community of different organisms, often in a particular biome and climate.True
100
Which organism is at the bottom of the ecosystem?
Plants
200
Beginning the wrist to the fingertips, what are the names of the hand bones?
Carpals, Metacarpals, and Phalanges
200
A longer set of phalanges would indicate that the animals hands and feets are designed to cover a ________surface area
Large
200
An carnivorous fish is less likely to survive if its teeth are...(hint: think about shape!)
It's teeth are not sharp enough
200
Why are animals adapted to certain ecosystems but not all ecosystem?
Animals adapt to what they have to survive
200
What are some abiotic components of an ecosystem?
Acceptable answers:
Water, soil, air, and sun
300
Why might we need so many bones in our wrist? (hint: twist, rotate, grasp...)
So our hand can rotate 360 degrees
300
Someone with longer arms and legs would be better at....
Any of the following is acceptable:
Running, grasping, reaching
300
Which animal is likely to survive in this scenario:
A long-legged deer is being chased by a small predator. Which one is likely to survive and why?
The long-legged deer because it can run faster
300
Every organisms works to 1) maintain balance or 2) survive.
Both
Maintain balance in order to survive
300
What two organisms would be in the middle of an ecosystem pyramid?
Primary Consumers and Secondary Consumers
400
If we have five fingers/phalanges on each hand, then evidence suggests that we would have __________ on each foot.
Toes/phalanges
400
A chimp has hands and feet that look more similar than different. What behavior do we engage in that they can't? 
Because chimps feet are not designed for walking, they are designed for grasping
400
Otters must learn to use rocks in order to crack open oysters and eat. Is this a trait they inherit or a behavior they learn?
A behavior they learn from their parents.
400
Why do predators play such a crucial role in ecosystems?
Acceptable answers:
They keep other animals in line
They control the population
They keep plant-eaters from eating everything
400
Use the scenario to determine which organism is a Primary Consumer and Secondary Consumer.
An elk is munching away at the bark of an Aspen Tree. A Grizzly Bear comes out from behind the Tree and begins chasing the deer down.
The Elk is the Primary Consumer because its eating a plant
The Grizzle Bear is a Secondary Consumer because it's trying to eat the Elk, which is meat

True or false
Even though frogs are not mammals, they also would have five phalanges.
True, but only on their back feet
500
A frog's legs are long, but typically in a crouching position. Their phalanges and metacarpals are long, covering more surface area? Why are they designed like this?
Because frogs are designed to jump and swim.
500
True or False:
Genetic Mutations can result in positive changes in an organism's body, allow it to survive in changing environments
True
500
Which of the following ecosystem roles is at the bottom of the ecosystem pyramid?
Primary Consumers, Primary Producers, or Producers?
Producers
500
What should happen if the Apex Predator-the Top Predator-become extinct from an Ecosystem?
The ecosystem would fall out of balance because all the organisms lower on the pyramid would not have another organism keeping them in check
