title: Comment on "Energy uptake and allocation during ontogeny".
abstract: Hou et al. (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.
