Models
A _________ is a simple model that shows how energy flows through an ecosystem
What is Food Chain
The first trophic level? The one in which organisms make their own food.
What is Producer?
Organisms that only eat plants
What is herbivore
The producer has 10,000 kcal of energy, how much is transferred to the primary consumer
What is 1,000 kcal or energy
A ___________ is a more complex model that represents the many interconnected food chains and pathways in which energy flows through a group of organisms
What is food web?
What is Primary Consumer
Organisms that only eat meat
What is carnivore
A primary consumer has 2,500 kcal of energy, what will the tertiary consumer have
What is 25 kcal of energy
The following is an example of?
Grass ----- Rabbit ----- Hawk ----- Cougar
What is food chain?
The organism that eats the primary consumer
What is secondary consumer
Organisms that eat both meat and plants
Omnivore
A producer has 27,000 kcal of energy, 3,000 is transferred to the primary consumer. What percentage of energy was transferred
What is 11%
A model showing the transferring of energy within an ecosystem
What is a food web?
The organism in the fourth trophic level
What is tertiary consumer
What is third-level consumer
The type of organism that makes up producers
What is autotroph
A primary consumer has 45,250 units of energy. The secondary consumer receives 8,500 units of energy from the primary consumer. What percentage was transferred
What is 18.8%
A diagram that can show the relative amounts of energy, biomass, or numbers of organisms at each trophic level in an organism
What is Ecological Pyramid?
Trophic levels do not go beyond tertiary or quaternary for this reason
What is not enough energy to transfer
The type of organism that makes up consumers
What is heterotroph
A secondary consumer receives 18.8% of energy from the primary consumer, what percentage of energy was not transferred.
What is 81.2%
