<jats:p> We demonstrate that the model of energy allocation during ontogeny of Hou <jats:italic>et al</jats:italic> . (Reports, 31 October 2008, p. 736) fails to account for the observed elevation of metabolic rate in growing organisms compared with similarly sized adults of different species. The basic model assumptions of the three-quarter power scaling for resting metabolism and constancy of the mass-specific maintenance metabolism need to be reassessed. </jats:p>

<jats:p> Hou <jats:italic>et al</jats:italic> . (Reports, 31 October 2008, p. 736) presented a model for energy uptake and allocation over an organism’s growth and development. However, their model does not account for allocation to reproduction (essential to adults) and growth without assimilation (essential to embryos) and is therefore only applicable to organisms growing with abundant food in the juvenile stage. </jats:p>

<jats:p> Our extended ontogenetic growth model is a theoretical model based on conservation of energy and general biological mechanisms underlying ontogenetic growth. We do not believe that the comments of Makarieva <jats:italic>et al</jats:italic> . and Sousa <jats:italic>et al</jats:italic> . expose substantive problems with our model. Nevertheless, they raise interesting, still unresolved questions and point to philosophical differences about the role of theory and of simple, general models as opposed to complicated, specific models. </jats:p>
