What is an adaptation?
A behavior or characteristic that helps an organism survive and reproduce in a specific environment.
100
What is a feature? Give 1 example.
A features is a structure, characteristic, or behavior of an organism. Ex. wings, eye color, fur pattern, timing of migration, etc...
100
What is a variation?
The range of expression of a trait within a population.
100
What is a population? Give 1 example.
A population is all the individuals of one kind in a specified area. Ex: A population of elephants in the African desert

Where do producers get their food from?
Producers use the energy from the sun to produce their own food through the process of photosynthesis.

What are two adaptations that a snail has?
1. It has a shell to hide from predators. 2. It excretes a layer of mucus to help it travel from one place to the next. 3. It can protect its eyes by turning them inside out.
200
What is a trait? Give one example of a trait.
A trait is a specific way that a feature is expressed in an individual organism. Ex: long/short wings, different eye colors, different number of spots, etc...
200
If eye color is a trait of humans, what would a variation of that trait be? Give 1 example.
An variation of that trait would be blue eyes, brown eyes, green eyes, etc...
200
What is an ecosystem? Give 1 example.
An ecosystem is a system of interacting organisms and nonliving factors in a specified area. Ex: ocean, mountain, swamp, etc...
200
What percent of energy is transferred from one trophic level to the next? Which trophic level has the most energy?
Only 10% of energy is transferred up the trophic levels. The trophic level with the most energy is that of the producers, who make their own food.
300
What is protective coloration? Give 1 example.
Protective coloration is an adaptation in some organisms that help them blend into their environment (Ex. octopus, walkingstick bugs, etc...)
300
What is a feature that is common to all walkingsticks?
They all have protective coloration, long/thin bodies to resemble sticks, six legs, etc...
300
Why is variation within a population so important for the survival of a species?
Variation within a population is important because it helps ensure that the best adapted species will survive and continue to reproduce.
300
What are three essential necessities that a species must have for its population to continue?
It must have water, food, shelter, a mate (reproduction), etc...

How do you know which is the correct way to point the arrows in a food web?
The arrows should always be pointing from the prey to the predator.
400
What is one human adaptation and one animal adaptation? How are they the same and how are they different?
One human adaptation: Sweat to cool off from the heat, a big toe to help balance, thumbs to pick up items, etc.. One animal adaptation: Wings to fly, thick fur/blubber to keep warm, webbed feet to swim quickly in the water, etc.. Similarities: Teeth to chew food, ears to hear when danger is approaching, eyes to see, etc...
400
Is this statement describing a feature or a trait? "Some dogs have shorter tails."
A feature of dogs would be that they have tails. However, this statement would be a trait because its describing a specific expression of tails within that species.
400
How does the variation in color (green, green/brown, and brown) in the walkingstick population affect its survival in the woodchip environment?
The population of brown walkingsticks are more likely to survive and reproduce because they blend in with their environment and can't be spotted as quickly by predators. The population of green and green/brown walkingsticks will get eaten more quickly because they stand out in their environment and will be seen by predators more easily.
400
What is a biotic factor? Name 3 things that make a biotic factor.
A biotic factor is any living thing. In order for it to be living, it must be able to eat, breathe, reproduce, excrete waste, etc...
400
If an organism is an omnivore, what level of consumer is it on the food web?
The organism would be a secondary level consumer because it eats both the producer and other organisms that eat producers.
500
A penguin's adaptation is color shading. Why is color shading important to its survival?
Color shading is important to a penguin's survival because the dark shade on the top of the penguin's body makes it blend in to the dark water below. The white part of its body makes it blend in to the sun above.
500
Is this statement a feature or a trait? "Walkingsticks have protective coloration."
This statement resembles a feature of walkingsticks. Traits of that feature would be different colors within the population like green, green/brown, and brown.
500
What is the difference between a structural and a behavioral adaptation? Give 1 example of each.
A structural adaptation refers to the physical structure of an organism Ex: long neck, spikes, fur, etc... A behavioral adaptation refers to how an organism behaves or acts Ex: Coyotes live in packs, sea otters anchor themselves to kelp, dogs bark to warn others of danger, etc...

What is the difference between a male and female milkweed bug?
A male has two black stripes on its belly and is usually smaller than the female. The female has one black stripe and two dots.
