    Hi,

    I was just wondering with energy transfer efficiency, why productivity is a better measure than pyramids of biomass and energy?
    I was thinking that firstly the net productivity could be compared and that it gives an indication of the energy available per area rather than just energy in total, as this would vary from different organisms due to size and activity levels?
    thank you

    Righto. Gross productivity can't be very well taken as an account of energy spent and assimilated. Net productivity, if split into separate bands (something which may be taken only for the sake of understanding) for each species, gives an account of energy lost and assimilated
