Back

Energy flow refers to the transfer of energy from one organism to another within an ecosystem, primarily through food chains and food webs.

What is the efficiency of energy transfer between trophic levels?

Back

The efficiency of energy transfer from one trophic level to the next is roughly 10%.

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the organism's role in the flow of energy, such as producer, primary consumer, or secondary consumer.

Front

What is a consumer in an ecosystem?

Back

A consumer is an organism that cannot produce its own food and must eat other organisms for energy.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy flows between various organisms.
