Transfer Of Biomass (biology Only) (GCSE Biology)

Which unit is most appropriate for expressing biomass of plants in a field?

When calculating ecological efficiency, you compare biomass at two successive trophic levels by dividing the higher-level biomass by the lower-level biomass and multiplying by 100. What does a result of 8% mean?

In aquatic food chains, why can the pyramid of biomass sometimes be inverted (small biomass of producers supports larger consumer biomass)?

Approximately what fraction of energy from one trophic level is typically transferred to the next trophic level?

What is `net primary productivity`?

Which practice increases the amount of biomass retained in a food chain and so improves efficiency for human food production?

Decomposers play an essential role in biomass transfer by

Which group makes biomass by photosynthesis at the base of most food chains?

What term describes the dry mass of living material in a trophic level per unit area?

Which farming change will most directly increase the proportion of solar energy captured as plant biomass?

A pyramid of biomass shows less total mass at higher trophic levels because
