Organizing data into visual representations and drawing conclusions is this important step
What is "Analyze Data?"
100
The blue line here refers to the population's _____________
What is carrying capacity?
(Make sure you can define this term!)
100
This type of organism derives its energy by consuming other organisms
What is a heterotroph?
(How is this different from an autotroph?)
100
This level of biological organization refers to all the organisms of one species living in the same ecosystem
What is a population?
(Do you know the other levels of biological organization?)
100
One reason biodiversity is valuable to ecosystems
The more biodiverse an ecosystem is, the more likely it is to adapt to change and survive (think coral reefs)

The first step of the scientific process
What is "Observe/Ask a question?"

This predator-prey interaction graph tells us that the relationship between these species is _______
Cyclical
200
This trophic level obtains their energy by hunting herbivores
What are secondary consumers?
(Can you name/describe the other trophic levels?)
200
trophic pyramid
or
energy pyramid

Barnacles growing on a whales back, receiving transportation and access to food, but not harming the whale, is an example of this interaction between species
What is commensalism?
(Do you know the other types of interactions between species?)
300
To share their findings with the world, scientists need to do this
What is "Report conclusions/Publish results?"

A. The wolf population change is affecting the elk population change
B. The elk population change is affecting the wolf population change

Give an example of a limiting factor for a population of maple trees
availability of sunlight, availability of water, disease, temperature, consumer population, etc.
(Make sure you can define limiting factors and identify them when necessary!)
300
Biotic or abiotic?
Biotic
300
These organisms get their energy from breaking down the detritus of other organisms
What are detritivores?
400
This group in an experiment is used as a baseline for measurement- no experiment is done on them.
What is the control group?
(Make sure you know- control vs. experimental group; independent vs. dependent variable)
400
What would cause the rabbit population to decrease over the first time unit (month) in the graph?
What is overpopulation of predators (there are too many snakes!)?
400
The trophic level of the monkey in this food web
What is quarternary?
(Do you know how to find a trophic level on a food web?)
400
An organism that consumes both plant and animal matter
What is an omnivore?
(Do you know the other types of feeding relationships?)
400
Herbivores that eat plants below them, as opposed to in front of or above them, are this type
What is a grazer?
Catfish are grazers.
Browsers are another type of herbivore.

This table shows the number of people with each shoe size in a class. What is the average shoe size?
What is 5.7?

The trend in the graph here suggests what?
The coral reef is warming and bleaching is increasing
500
On average, this % of energy flows from one trophic level to the next
What is 10%?
(REMEMBER this is just a rule of thumb- we've seen examples where this is not true)

Without this population, an ecosystem can collapse
What is a keystone species?
(What examples of keystone species do you know?)
