  2. Primary nutritional groups - Wikipedia

    en.wikipedia.org/wiki/Primary_nutritional_groups

    Chemotrophs release chemical energy. The freed energy is stored as potential energy in ATP, carbohydrates, or proteins. Eventually, the energy is used for life processes such as moving, growth and reproduction. Plants and some bacteria can alternate between phototrophy and chemotrophy, depending on the availability of light.

  3. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / 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.

  4. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    28.2% (sunlight energy collected by chlorophyll) → 68% is lost in conversion of ATP and NADPH to d-glucose, leaving; 9% (collected as sugar) → 35–40% of sugar is recycled/consumed by the leaf in dark and photo-respiration, leaving; 5.4% net leaf efficiency. Many plants lose much of the remaining energy on growing roots.

  5. Bioenergy - Wikipedia

    en.wikipedia.org/wiki/Bioenergy

    Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] 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.

  6. Autotroph - Wikipedia

    en.wikipedia.org/wiki/Autotroph

    Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water (green arrow). An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms.

  7. Plant-based diet - Wikipedia

    en.wikipedia.org/wiki/Plant-based_diet

    A plant-based diet is a diet consisting mostly or entirely of plant-based foods. [ 1 ] [ 2 ] It encompasses a wide range of dietary patterns that contain low amounts of animal products and high amounts of fiber-rich [ 3 ] plant products such as vegetables , fruits , whole grains , legumes , nuts , seeds , herbs, and spices .

  8. 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 .

  9. Biomass partitioning - Wikipedia

    en.wikipedia.org/wiki/Biomass_partitioning

    Biomass partitioning is the process by which plants divide their energy among their leaves, stems, roots, and reproductive parts.These four main components of the plant have important morphological roles: leaves take in CO 2 and energy from the sun to create carbon compounds, stems grow above competitors to reach sunlight, roots absorb water and mineral nutrients from the soil while anchoring ...
