Transfer Of Biomass (biology Only) (GCSE Biology)

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

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

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

Which statement about respiration and biomass is correct?

If 2000 kJ of energy is available to herbivores from plant biomass and consumers convert 10% of this into their own biomass, how much energy enters the next trophic level?

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

Which human activity typically reduces the transfer efficiency from primary producers to consumers?

An ecosystem has a large amount of primary productivity but low transfer to consumers. Which feature could explain this?

Why do scientists often use dry mass rather than fresh mass when measuring biomass?

If a field supports 1000 kg of plant biomass and a grazing herd converts 10% of that per year into animal biomass, how much animal biomass could be produced in a year (assuming perfect retention)?

What is the main reason most biomass is not passed on to the next trophic level?
