10% Rule and Energy Flow Through Ecosystems

Front

What is the 10% Rule in energy transfer?

Back

The 10% Rule states that only about 10% of the energy from one trophic level is transferred to the next level in an ecosystem.

Front

What are food webs made of?

Back

Food webs are made of interconnected food chains that show how energy and nutrients flow through an ecosystem.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own energy from non-living sources, such as sunlight or inorganic compounds.

Front

What is a heterotroph?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What is a producer in an ecosystem?

Back

Producers are organisms, typically plants, that create energy through photosynthesis and form the base of the food chain.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers (plants) and are the second trophic level in a food chain.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers and are typically carnivores or omnivores.

Front

What are tertiary consumers?

Back

Tertiary consumers are predators that eat secondary consumers and are at the top of the food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the flow of energy and nutrients.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another.
