Energy pyramids/trophic levels

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy through different trophic levels in an ecosystem.

Front

What percentage of energy is typically transferred from one trophic level to the next?

Back

10%.

Front

What happens to the remaining energy that is not transferred to the next trophic level?

Back

It is lost as heat or used by the organism for metabolic processes.

Front

What is the primary source of energy in an energy pyramid?

Back

Producers, such as plants, algae, and phytoplankton.

Front

What are trophic levels?

Back

Trophic levels are the different levels in an ecosystem that represent the flow of energy from producers to various levels of consumers.

Front

What type of consumer receives energy directly from producers?

Back

Herbivores.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers, such as herbivores.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers, such as carnivores.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers, often at the top of the food chain.

Front

How much energy is lost as heat or used by organisms at each trophic level?

Back

90%.
