  2. Energy flow (ecology) - Wikipedia

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

    Energy flow is the flow of energy through living things within an ecosystem. [1] All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. [2] [3] Each of the levels within the food chain is a trophic level. [1] In order to more efficiently show the quantity ...

  3. Earth's energy budget - Wikipedia

    en.wikipedia.org/wiki/Earth's_energy_budget

    Definition. Earth's energy budget includes the "major energy flows of relevance for the climate system". These are "the top-of-atmosphere energy budget; the surface energy budget; changes in the global energy inventory and internal flows of energy within the climate system".

  4. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    The first law of thermodynamics asserts that the total energy of a system and its surroundings (but not necessarily thermodynamic free energy) is always conserved and that heat flow is a form of energy transfer.

  5. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Bernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid is the same at all points that are free of viscous forces. This requires that the sum of kinetic energy, potential energy and internal energy remains constant.

  6. Ecosystem - Wikipedia

    en.wikipedia.org/wiki/Ecosystem

    t. e. An ecosystem (or ecological system) is a system that environments and their organisms form through their interaction. [2] : 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.

  7. Nutrient cycle - Wikipedia

    en.wikipedia.org/wiki/Nutrient_cycle

    A nutrient cycle (or ecological recycling) is the movement and exchange of inorganic and organic matter back into the production of matter. Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic. Mineral cycles include the carbon cycle, sulfur cycle, nitrogen cycle, water cycle, phosphorus ...

  8. Poynting vector - Wikipedia

    en.wikipedia.org/wiki/Poynting_vector

    Electromagnetism. In physics, the Poynting vector (or Umov–Poynting vector) represents the directional energy flux (the energy transfer per unit area, per unit time) or power flow of an electromagnetic field. The SI unit of the Poynting vector is the watt per square metre (W/m 2 ); kg/s 3 in base SI units.

  9. Energy flow - Wikipedia

    en.wikipedia.org/wiki/Energy_flow

    Energy flow may refer to: Energy transfer, the transfer of physical energy from one body or place to another. Energy flow (ecology), the flow of energy through a biological food chain. Energy (esotericism) flow, the movement of spiritual energy. Fluid dynamics, energy of a flowing fluid related to pressure.
