    en.wikipedia.org/wiki/Standing_crop

    A standing crop is the total biomass of the living organisms present in a given environment. [1] This includes both natural ecosystems and agriculture. See also

  3. Biomass (energy) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(energy)

    Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]

    In the Food, Conservation, and Energy Act of 2008 (Pub. L. 110–234 (text)), the federal government created a program to help guarantee this supply, called the Biomass Crop Assistance Program (BCAP). As with the RFS, investors in the market are reluctant to place money in a currently unproven technology, or are reluctant to dedicate other ...

  5. Theoretical production ecology - Wikipedia

    en.wikipedia.org/wiki/Theoretical_production_ecology

    Standing crop biomass – Unlimited growth is an exponential process, which means that the amount of biomass determines the production. Because an increased biomass implies higher respiration per surface unit and a limited increase in intercepted light, crop growth is a sigmoid function of crop biomass.

  6. Biomass - Wikipedia

    en.wikipedia.org/wiki/Biomass

    Biomass is a term used in several contexts: in the context of ecology it means living organisms, [1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, [ 2 ] from plants and algae, [ 3 ] from plants and ...

  7. Bioenergy - Wikipedia

    en.wikipedia.org/wiki/Bioenergy

    The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. [3]

  8. Energy flow (ecology) - Wikipedia

    en.wikipedia.org/wiki/Energy_flow_(ecology)

    Secondary production is the use of energy stored in plants converted by consumers to their own biomass. Different ecosystems have different levels of consumers, all end with one top consumer. Most energy is stored in organic matter of plants, and as the consumers eat these plants they take up this energy.
