Pyramids Of Biomass (biology Only) (GCSE Biology)

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

What does an inverted pyramid of biomass indicate in an ecosystem?

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

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

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

When ecologists compare pyramids of biomass across different ecosystems, what valuable conclusion can they most reliably draw?

Which process primarily causes biomass to decrease between trophic levels?

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?

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

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

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