Figure 1 in Could Tyrannosaurus rex have been a scavenger rather than a predator? An energetics approach

Figure 1. The minimum energy density that the ecosystem must provide to allow energy balance of the scavenger as a function of the distance in metres at which carrion can be detected, calculated from equation (2.7). The abscissa is logarithmic to the base 10 so '1' represents 10 m, '2' 100 m, '3' 1 km and '4' 10 km.
