Metabolism is worked out using BMR. BMR stands for your basal metabolic rate. This is the amount of cals you burn doing nothing, just allowing your body to run.
The larger you are (weight or height) the higher your BMR will be.
The older you are the lower your BMR will be due to muscle loss year on year.
If you have a lot of muscle compared to fat your BMR will be higher.
metabolism and size of individual in an ecosystem
Your metabolism is how fast your body turns food into energy. I don't know what you mean by "size of indiviual."
Size does effect metabolism rates. The smaller the animal the less energy its metabolism expends. Bigger animals must have a more active metabolism to regulate themselves, and it correlates with expected lifespans.
Days... depending on the metabolism of the individual !
Metabolism.
Gender, age and body size and type
The amount of energy required to maintain an individual in a resting state.
It can be possible if they have worked out and ate well, because this individual is so young there metabolism is constantly going. As the individual gets older, it is very unlikely that they will be able to do such because their metabolism will start to slow.
it is metabolism
regulation
There appears to be no metabolism booster products free of caffeine. However, an individual could boost metabolism naturally in a number of ways. Examples would include exercise, eating right, drinking a lot of water and getting plenty of sleep.
