Which trophic level comes after primary producer?
What is primary consumer

A food web shows the transfer of ________ between organisms in an ecosystem
What is energy?
100
These organisms make their own energy
What is autotrophs
100
These consumers eat only plants
What are herbivores

What is the difference between a food web and a food chain?

A food chain is one line of energy transfers. A food web describes a complex interaction of many food chains in an ecosystem

What trophic level is always at the bottom of an energy pyramid?
What is producers
200
What option describes the flow of energy in an ecosystem? a. Producers-->Primary Consumers-->Secondary Consumers b. Secondary Consumers-->Primary Consumers-->Producers c. Primary Consumers-->Producers-->Secondary Consumers
What is A
200
These organisms do not make their own energy and rely on consuming other organisms to make energy
What is heterotrophs
200
These consumers only eat meat
What are carnivores

In a typical energy pyramid, the relative amount of energy that is transferred from each trophic level to the next

What is 10%

300
A trophic level represents a a. Consumer b. Chemical cycle c. Feeding level
What is C
300
How do most producers make/get their energy?
What is from the sun (through photosynthesis)
300

Algae, grass, and trees are examples of

What are autotrophs?

300
These consumers eat plants and animals
What are omnivores

A bird stalks, kills, and then eats an insect. Based on its behavior, which pair of ecological terms describe this bird A. herbivore, decomposer                                           B. producer, heterotroph                                             C. carnivore, consumer                                               D. autotroph, herbivore

What is C?

400
The trophic level that contains the largest biomass (number of organisms) is
What is producers
400
This percent of energy is transferred between trophic levels
What is 10%
400

Animals, Fungi, and most bacteria are examples of

What are heterotrophs?

400
These consumers get energy by eating the carcasses of other animals that have been killed by predators or have died of natural causes classified as
What are scavengers
400

Identify the process that a producer can carry out that a consumer cannot

What is photosynthesis?

500
What is the total amount of living material within a given trophic level called?
What is biomass?
500
90% of energy is lost to the environment as ______ between trophic levels
What is heat
500

Another word that means the same as autotroph

What is producer?

500
These consumers feed on dead and decaying organisms
What are decomposers
500

Explain the 10% rule and how energy flows through an ecosystem

The 10% rule states that only 10% of energy is transferred between trophic levels. 90% of energy is lost as heat to the environment.
