CH 3.2 SAVVAS TEST-Energy Flow in Ecosystems: DIGITAL

Front

What happens to the population of grasshoppers if frogs become extinct?

Back

The population of grasshoppers will increase.

Front

Which organisms have the most energy available in an energy pyramid?

Back

Producers have the most energy available.

Front

What is a pyramid of biomass?

Back

A graphical representation showing the biomass at each trophic level in an ecosystem.

Front

How does energy flow in an ecosystem with four trophic levels?

Back

About ten percent of the energy at one trophic level is passed to the next trophic level.

Front

What level does energy flow to directly after the producer level?

Back

Energy flows directly to the primary consumer after the producer level.

Front

Define producers in an ecosystem.

Back

Producers are organisms that create their own food through photosynthesis, such as plants.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers.

Front

What role do secondary consumers play in an ecosystem?

Back

Secondary consumers are carnivores that eat primary consumers.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

Explain the concept of trophic levels.

Back

Trophic levels are the hierarchical levels in an ecosystem, comprising producers, primary consumers, secondary consumers, and decomposers.
