In ecology, biomass refers to the mass of organisms living within a specific region at a time. Biomass is measured and usually described as:
the total mass of the organisms within a community
the average masses per unit area
Typically, more numerous organisms, such as producers, have a higher average biomass. This may include plants, animals or microbes such as bacteria and fungi. In terrestrial environments, biomass is distributed in pyramid form; the carnivorous hawk preys on rabbits and birds, which are nearer to the base of the pyramid- each predator population would have a lower biomass than its prey.
The birds weigh 100 grams while the rabbit weighs 150 grams.The rabbit has a higher total mass
The "set-point theory" implies that each individual is genetically programmed to carry a particular amount of body weight.
The set point is the weight range in which your specific body is programmed to work. The set point theory trusts that a man's body will battle to keep up that specific weight range.
