Pyramids Of Biomass (biology Only) (GCSE Biology)

Which trophic level would you expect to have the smallest total biomass in most ecosystems?

Which best explains why energy pyramids and biomass pyramids are related but not identical?

Why are pyramids of biomass usually measured using dry mass rather than wet mass?

Why is the “10% rule” (about 10% energy transfer between trophic levels) only an approximation?

For a pyramid of biomass based on a grassland, which sampling method would give the most reliable producers’ biomass estimate?

Which term describes the total mass of living material in a trophic level?

A scientist measured biomass at one time in a rapidly reproducing producer population (e.g., algae) and found a small producer biomass but large consumer biomass. What is the most likely explanation?

Which method is least appropriate for constructing a pyramid of biomass for aquatic phytoplankton?

How can harvesting of primary producers (e.g., cutting grass for silage) change the pyramid of biomass on a farm?

Why might a logged forest show a temporary increase in biomass of herbaceous plants but a decrease in total standing biomass?

In a typical food chain, which trophic level forms the base of a pyramid of biomass?
