How does the amount of energy change as it moves up an energy pyramid?
Stays the same
Decreases
Increases
How much energy is passed on from one trophic level to the next?
80%
10%

none
An energy pyramid shows the loss of energy at each trophic level. Why is energy not really lost?
Some energy is converted into waste and heat energy.
Some energy goes back to the sun.
Some energy is recycled.
All energy gets transfered to the next organism.
What type of succession occurs from newly formed rock and no soil?
Primary
Secondary
Tertiary
Quaternary
When two animals fight for a mate:
Symbiosis
Parasitism
Commensalism
Competition
What is the main way energy is lost in a food chain?
It gets lost in the woods.
It is lost as energy goes back to the sun.
It is lost as heat during cellular respiration.
It gets lost as atmospheric heat.
In a food chain, what is the role of the plant?
Consumer
Heterotroph
Producer
Primary consumer
What type of organisms make their own food using the sun's energy?
Decomposer
Autotroph
Omnivore
Carnivore
There are usually no more than four trophic levels in a food chain. Why?
Energy gets lost (metabolism) and too many links cannot be supported.
Energy is gained (metabolism) and too many links cannot be supported.
