100
Put these in order in a pyramid.
Primary Consumers, Tertiary Consumers, Producers, Secondary Consumers
What is:
Producers --> Primary -> Secondary -> Tertiary
100
Name the autotroph and two heterotrophs
What is...
Grass (Autotroph)
Literally Any animal (heterotroph)
100
The law that states that energy cannot be created nor destroyed, AND how it applies to ecosystems.
What is the law of conservation of energy.
What is energy is never lost. Even if it is not made available to the next organism in the food chain, it is returned to the environment as heat, and/or is recycled by decomposers.
200
Where the 90% of energy that is not made available to organisms in the next trophic level goes.
What is to the environment as heat?
200
Owls, Bird, Fox, Hawk
300
The relationship between trophic levels, energy, and biomass as you move up the pyramid.
What is:
The biomass decreases as you move up the trophic levels, and the amount of energy that is available decreases, as well as there are less organisms.
10% of whatever energy is available is still transferred.
300
One difference and one similarity between food web and food chain.
What is:
Both show energy transfer.
Food webs: show interactions of all organisms
Food Chains: show only one energy pathway
400
The number of kcals of energy available to the third trophic level if the food chain begins with 20,000 kcals.
What is 200 kcals.
(20,000 x 0.1 x 0.1)
400
The effect of having too many sharks in a coral reef.
What is:
There will not be enough energy for them. So they will die out.
500
Make a food chain with 5 organisms.
What is...
Plankton --> Krill --> Squid --> Penguin --> Seal
500
What is:
Less energy for snakes
More grasshoppers
less grass
