Document Summary
Objective 3a: calculate the components of an energy budget, and use results to assess how biomass changes will be affected. Einput = ermr + eactivity + egrowth + ereproduction + eexcretion. Eprodcution = egrowth + ereproduction: consider how components of the energy budget are traded off or positively related, and how an organism"s life history might explain these. Energy must be traded off for the various components of life. Ex: not all energy can be used for growth because some energy must be used for activity in order to get food: describe why minimal (resting, basal) metabolism is a non-negotiable part of an organisms energy allocation. Hypothesis tells us that more activity results in scaling closer to 0. 67 while less activity results in scaling closer to 1. 0 so it is always fluctuating depending on activity level. U-shaped graph: minimal mr (cid:314) low rmr (cid:314) high rmr (cid:314) active.
