Webratio throughout the trophic levels, i.e., typically from 2.5% to 5% greater [11,12]. Carbon signatures show little change with trophic level but can be very useful indicators of the dietary source of carbon [10,13].

A trophic pyramid (a) and a simplified community food web (b) illustrating ecological relations among creatures that are typical of a northern Boreal terrestrial ecosystem. The trophic pyramid roughly represents the biomass (usually measured as total dry-weight) at each level. Plants generally have the greatest biomass.
