1.
True or False. In this energy pyramid, the consumers on each level only get about 10 percent of energy that the trophic level before it has stored.
a)
True
b)
False
2.
A pyramid shape is used to show the amount of available energy at each trophic level because...
a)
energy decreases as you go up the food chain, just like the pyramid shape gets smaller as you go up.
b)
energy increases up the food chain just like the pyramid shape gets smaller as you go up.
c)
energy amounts are the same at each trophic level
3.
In this energy pyramid, what is the proper name for ANY ORGANISM ABOVE THE PRODUCER LEVEL?
a)
decomposers
b)
consumers
c)
producers
d)
omnivores
4.
What makes an energy pyramid different than a food web or chain?
a)
It shows energy flowing from the top of the chain and downward.
b)
The tropic levels are the opposite
c)
It shows the amount of energy in each trophic level
d)
It shows specific predator/prey relationships
5.
What is the sun's role in the energy pyramid?
a)
to produce chemical energy for the ecosystem.
b)
to provide radiant energy for producers to convert to chemical energy.
c)
to start the energy flow of the ecosystem.
d)
to provide mechanical energy for producers to convert to chemical energy.
6.
In the energy pyramid below, which organism has the least amount of energy available?
a)
Producers
b)
Herbivores
c)
Carnivores
d)
Top Predator
7.
Based on the model, which consumers would receive the greatest amount of energy captured by the producers in their food chains?
a)
Beluga Whale
b)
Polar Bear and Arctic Hare
c)
Ptarmigan and Arctic Bumble
d)
Lichens and Shrubs
8.
In the energy pyramid here, which organisms have the most energy available?
a)
Producers
b)
Carnivores
c)
Herbivores
d)
Top Predator
9.
How much energy is lost when organisms consume another organism from a different level?
a)
90%
b)
20%
c)
50%
d)
10%
10.
If only 10% of an organism's energy is available for the next trophic level, what happens with the other 90% of the energy?
a)
It is destroyed after it is used up.
b)
It is used for life processes or lost as body heat.
c)
It remains for the next trophic level IF the predator consumes ALL of the organism.
d)
It is lost completely as body heat.
