  2. Liebig's law of the minimum - Wikipedia

    en.wikipedia.org/wiki/Liebig's_law_of_the_minimum

    Liebig's law states that growth only occurs at the rate permitted by the most limiting factor. [2] For instance, in the equation below, the growth of population O {\displaystyle O} is a function of the minimum of three Michaelis-Menten terms representing limitation by factors I {\displaystyle I} , N {\displaystyle N} and P {\displaystyle P} .

  3. Limiting factor - Wikipedia

    en.wikipedia.org/wiki/Limiting_factor

    Limiting factor. A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on. A factor not limiting over a certain domain of starting conditions may yet be limiting over ...

  4. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von ...

  5. Redfield ratio - Wikipedia

    en.wikipedia.org/wiki/Redfield_ratio

    Note that nitrate is more often limiting than phosphate. The Redfield ratio or Redfield stoichiometry is the consistent atomic ratio of carbon, nitrogen and phosphorus found in marine phytoplankton and throughout the deep oceans. The term is named for American oceanographer Alfred C. Redfield who in 1934 first described the relatively ...

  6. Limnology - Wikipedia

    en.wikipedia.org/wiki/Limnology

    Phosphorus has a different role in aquatic ecosystems as it is a limiting factor in the growth of phytoplankton because of generally low concentrations in the water. Dissolved phosphorus is also crucial to all living things, is often very limiting to primary productivity in freshwater, and has its own distinctive ecosystem cycling.

  7. Eutrophication - Wikipedia

    en.wikipedia.org/wiki/Eutrophication

    This means that some nutrients are more prevalent in certain areas than others and different ecosystems and environments have different limiting factors. Phosphorus is the limiting factor for plant growth in most freshwater ecosystems, and because phosphate adheres tightly to soil particles and sinks in areas such as wetlands and lakes, due to ...

  8. Deep chlorophyll maximum - Wikipedia

    en.wikipedia.org/wiki/Deep_chlorophyll_maximum

    The vertical mixing of limiting nutrients across the thermocline is a key process in supporting the deep water chlorophyll maximum. This mixing can be driven by a number of processes linked to wind driven oscillations, internal tides and entrainment through the deepening of the surface mixed layer.

  9. Primary production - Wikipedia

    en.wikipedia.org/wiki/Primary_production

    The factors limiting primary production in the ocean are also very different from those on land. The availability of water, obviously, is not an issue (though its salinity can be). Similarly, temperature, while affecting metabolic rates (see Q 10 ), ranges less widely in the ocean than on land because the heat capacity of seawater buffers ...
