One of these assumes energy or resource transport across the external surface area of three-dimensional organisms is the key factor driving the relationship between metabolic rate and body size. The surface area in question may be skin, lungs, intestines, or, in the case of unicellular organisms, cell membranes.

Kleiber's plot comparing body size to metabolic rate for a variety of species. [1]Kleiber's law, named after Max Kleiber for his biology work in the early 1930s, states, after many observations that, for a vast number of animals, an animal's Basal Metabolic Rate scales to the 3 ⁄ 4 power of the animal's mass.
It is assumed that evolution by natural selection results in animals utilizing the most economic and efficient strategy to balance energy gain and consumption. The Marginal Value Theorem is an optimality model that describes the strategy that maximizes gain per unit time in systems where resources, and thus rate of returns, decrease with time ...
If Riker accepts them, Q wins command of the starship; if he refuses them, Picard makes Q promise to never interfere with humanity again. Meanwhile, Riker and his team are attacked by what Lt. Worf reports as "vicious animal things" dressed as Napoleonic soldiers wielding energy-firing muskets. Q returns to Riker and tells him that he has ...
Even though energy is briefly stored in stretched elastic elements are also released, there is an overall net gain. This shows that muscle fibers are effective in both power production and for energy consumption utilized by the body or individual body segments with muscle-tendon units. [1]
As Hurricane Milton strengthens in the Gulf of Mexico, AccuWeather meteorologists are deeply concerned about the possibility of rapid intensification because of the warm temperatures of the water.
The exact mechanism is still a topic of debate but the most widely accepted theory is that the archaea use the reversed methanogenesis pathway to produce carbon dioxide and another, unknown intermediate, which is then used by the sulfate-reducing bacteria to gain energy from the reduction of sulfate to hydrogen sulfide and water.
