Pyramids of number, Biomass and Energy

What is a food chain

A food chain shows what is eaten by what in an ecosystem

What is an example of a producer, primary consumer and secondary consumer

producer = dandelions

primary consumer = rabbits

secondary consumer = fox

What does a pyramid of numbers show

Each bar on the pyramid of numbers shows the number of organisms at that stage of the food chain

What does the pyramid of biomass show

Each bar on a pyramid of biomass shows the mass of living material at that stage of the food chain

What is the energy transfer between each trophic level

the energy transferred at each trophic level is the energy that is lost compared to what is transferred to the next consumer (less energy is transferred each time)

What is a trophic level

the position of an organism in a food chain

How is the energy lost at each trophic level

It is released in respiration of the organism and in heat release
