The rate of photosynthesis on the other hand, indicates the metabolic rate of an autotroph. [6] According to MTE, both body size and temperature affect the metabolic rate of an organism. Metabolic rate scales as 3/4 power of body size, and its relationship with temperature is described by the Van't Hoff-Arrhenius equation over the range of 0 to ...
Ecosystem respiration is the sum of all respiration occurring by the living organisms in a specific ecosystem. [1] The two main processes that contribute to ecosystem respiration are photosynthesis and cellular respiration. Photosynthesis uses carbon-dioxide and water, in the presence of sunlight to produce glucose and oxygen whereas cellular ...
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, is the observation that, for the vast majority of animals, an animal's metabolic rate scales to the 3 ⁄ 4 power of the animal's mass. [2]
The Streeter–Phelps equation determines the relation between the dissolved oxygen concentration and the biological oxygen demand over time and is a solution to the linear first order differential equation [1] This differential equation states that the total change in oxygen deficit (D) is equal to the difference between the two rates of ...
The rate ratio at a temperature increase of 10 degrees (marked by points) is equal to the Q10 coefficient. The Q10 temperature coefficient is a measure of temperature sensitivity based on the chemical reactions. The Q10 is calculated as: where; T is the temperature in Celsius degrees or kelvin. Rewriting this equation, the assumption behind Q10 ...
Photosynthesis (/ ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [ 1 ] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Lake metabolism represents a lake 's balance between carbon fixation ( gross primary production) and biological carbon oxidation ( ecosystem respiration ). [1] Whole-lake metabolism includes the carbon fixation and oxidation from all organism within the lake, from bacteria to fishes, and is typically estimated by measuring changes in dissolved ...
The relationship between Fick's law and semiconductors: the principle of the semiconductor is transferring chemicals or dopants from a layer to a layer. Fick's law can be used to control and predict the diffusion by knowing how much the concentration of the dopants or chemicals move per meter and second through mathematics.
