Document Summary

How do individual organisms use energy: maintenance- using energy to maintain order against tendency towards a greater state of entropy. Ectothermic: use environment energy flows to maintain body temperature: source of energy: conduction, convection, radiation, can endure range of body temperatures, high efficiency, low basal metabolic rate, active period, surplus energy. Endothermic: generate their own body temperature by burning food to maintain a relatively constant body temperature: source of energy: respiration, must maintain fairly constant temperature, low efficiency, high basal metabolic rate, active period, and surplus energy, growth. Metamorphosis: changes in body form that accompany maturation. Energy stored for periods when food is less available. Most energy is stored as carbohydrates: easier to move around through fluids. Most energy is stored as fat: fat has a high storage capacity. Ways to deal with seasonal energy differences. Mimicry: red touches yellow kill a fellow, red touches black friend of jack . Allocating energy to produce and care for offspring.
