Energy Roles
What types of organisms are producers?
What are plants?
I eat only plants. What am I?
What is a herbivore
a series of events in which one organism eats another and obtains energy.
What is a food chain.
Quickly create a 3 link food chain.
Algae -> tadpole -> heron
The amount of energy that is used up or lost to the environment.
what is 90%
I eat only other animals. What am I?
What is a Carnivore?
many overlapping food chains in an ecosystem.
What is food web.
How do organisms obtain energy?
What is by consuming/eating.
The amount of energy passed from one trophic level to another.
What is 10%
True or False. Producers are the source of all the food in an ecosystem.
What is True.
I eat both plants and animals. What am I?
What is an omnivore?
Double Jeopardy: a diagram that shows the amount of energy that moves from one feeding level to another in a food web.
What is an energy pyramid.
Double Jeopardy: How much energy is transferred from one organism to another when feeding on one another?
What is 10 percent.
The organisms that are found on the side of the energy pyramid
What is decomposers
List two classic decomposers.
Bacteria, earthworms, fungi
An organism that gets food by breaking down dead organisms into small molecules.
What is a decomposer
Which diagram is a more realistic portrayal of how an ecosystem transfers energy: food web or food chain? Explain.
What is food web.
Identify the energy roles of the following organisms in a pond ecosystem: tadpole, algae, heron.
algae: producer
Tadpole: herbivore/primary consumer
Heron: carnivore/ secondary consumer
The trophic level with the most available energy and the most organisms
What is producers
What are the three energy roles all organisms in the ecosystem fit into?
What are producers, consumers, and decomposers.
I eat dead organisms but do not bring nutrients back to the earth. What am I?
What is a scavenger?
Each level in an Energy pyramid is called
What is a trophic levels
Why is the pyramid shape useful for showing the energy available at each level of a food web?
Bio Mass and population decrease as you go up the energy pyramid
NOT including decomposers, what are the four trophic levels we have discussed in class
Producers, Primary Consumers, Secondary Consumers, Tertiary Consumers
