Food Chains
Who Am I?
The Great Pyramid
Because - Why?
How much do I get?
100
The flow of energy starts with
What is the sun?
100
I am the source of all energy.
What is the sun?
100
I am the name of each level and an energy pyramid.
What is a trophic level?
100
because I produce the food source of energy for the entire food web or energy pyramid.
Why is the producer/autotroph the largest trophic level in an energy pyramid?
100
The producer has 2,450 kcals. I am the herbivore.
What is 245 kcals?
200
Which organism is the producer?
What are leaves or what are autotrophs?
200
I have the greatest amount of energy and make my own food.
What is a producer? or What is an autotroph?
200
I am the largest trophic level.
What is a producer/autotroph?
200
because 90% is lost to heat and other functions.
Why is only 10% of the energy passed to each trophic level?
200
The herbivore has 1,000 kcals. I am the secondary consumer.
What is 100 kcals?
300
This organism preys on the mouse.
What is an owl?
300
I consume/eat only the producers/autotrophs.
What is an herbivore?
300
I am a top level predator.
What is an apex predator?
300
because there is less energy at the top of the food chain.
Why is it a pyramid or why are the top trophic levels smaller than the bottom trophic level?
300
I convert energy from the sun into chemical energy glucose. So I get it all.
What is 100%?
400
The names of the trophic levels are
What is producer, primary consumer, secondary consumer, tertiary consumer, detritivore.
400
I eat meat and autotrophs.
What is an omnivore?
400
I am at every trophic level.
What is a decomposer/detritivore?
400
because I produce my own food through photosynthesis.
Why am I called a producer?
400
I get the smallest amount of energy.
What is the apex predator?
500
The arrows in a food chain show
What is the direction of energy flow?
500
I return nutrients to the soil by breaking down dead organisms.
What is a detritivore?
500
I am the 4th trophic level.
What is a tertiary consumer?
Producer - Level 1
Primary - Level 2
Tertiary - Level 3
500
because my prefix means both. In flow of energy I eat both producers and animals.
Why am I called and omnivore?
500
I take a lot of the energy that transfers from one trophic level to the next.
What is heat?
