Determine the type of growth that is being shown. A rabbit population grows rapidly after being introduced to an island with lots of food and no predators.
What is exponential growth?
A lion hunting and eating a zebra is an example of this density-dependent factor.
What is predation?
The percentage of energy transferred to each level & the percentage lost as heat.
What is...
Energy transfer: 10%
Lost as heat: 90%
In the Carbon Cycle...
Photosynthesis takes in _____ and releases ______
Cellular Respiration takes in ______ and releases ____
What is...
Photosynthesis takes in CO2 and releases O2
Cellular Respiration takes in O2 and releases CO2
Draw what an exponential growth & logistics growth graph looks like. Include axis titles!
What is...

The type of symbiotic relationship that is found in the following: A remora fish attaches to a shark and eats leftover scraps of food while traveling long distances with it.
What is commensalism?
If the primary consumer has 10,000 kcal of energy in a food web, determine the energy transfer for the remaining trophic levels, up to the tertiary consumer.
What is...
Producer: 100,000
Secondary Consumer: 1,000
Tertiary Consumer: 100
This cycle mostly happens underground with bacteria.
+100 Bonus points if you can tell me what process is involved with this cycle, changing N2 to NH3
What is the nitrogen cycle?
Bonus point: nitrogen fixation
Determine an example of a density-dependent factor and a density-independent factor.
What is...
Density-dependent: competition, predation, or disease
Density-independent: natural disasters, human disturbance
The factors of population growth that cause a decrease in the population are:
What is...
# of deaths & emigration
Put these organisms in the correct food chain order and assign them their correct trophic level:
hawk, grass, mouse, snake.
What is...
grass (producer) --> mouse (primary consumer) --> snake (secondary consumer) --> hawk (tertiary consumer)
The difference between energy flow and the flow of matter
What is...
- Energy flow: flows in one direction & is lost as heat
- Flow of Matter: can be recycled & transformed
Define the three types of symbiotic relationships
Bonus +200 points for providing an example of each.
What is...
Mutualism: both benefit
Parasitism: one benefits, the other is harmed
Commensalism: one benefits, the other is unaffected
The cycle that is most directly affected when a farmer uses large amounts of fertilizer, and after heavy rain, the fertilizer washes into nearby lakes and rivers
What is the phosphorus cycle?
