  2. Reflux - Wikipedia

    en.wikipedia.org/wiki/Reflux

    The reflux system in a typical industrial distillation column. Reflux is a technique involving the condensation of vapors and the return of this condensate to the system from which it originated. It is used in industrial [1] and laboratory [2] distillations. It is also used in chemistry to supply energy to reactions over a long period of time.

  3. Food chain - Wikipedia

    en.wikipedia.org/wiki/Food_chain

    Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...

  4. Fractional distillation - Wikipedia

    en.wikipedia.org/wiki/Fractional_distillation

    The reflux flowing downwards provides the cooling required for condensing the vapors flowing upwards. The reflux ratio, which is the ratio of the (internal) reflux to the overhead product, is conversely related to the theoretical number of stages required for efficient separation of the distillation products.

  5. Organic synthesis - Wikipedia

    en.wikipedia.org/wiki/Organic_synthesis

    Reflux occurs when condensation can be seen dripping back into the reaction flask from the reflux condenser; 1 drop every second or few seconds. [19] For recrystallization, the product-containing solution is equipped with a condenser and brought to reflux again. Reflux is complete when the product-containing solution is clear.

  6. Energy flow (ecology) - Wikipedia

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

    There are two major food chains: The primary food chain is the energy coming from autotrophs and passed on to the consumers; and the second major food chain is when carnivores eat the herbivores or decomposers that consume the autotrophic energy. [16] Consumers are broken down into primary consumers, secondary consumers and tertiary consumers.

  7. Reflux (disambiguation) - Wikipedia

    en.wikipedia.org/wiki/Reflux_(disambiguation)

    Reflux is a term meaning "to flow backwards" or "to return". In chemistry, reflux is a distillation technique involving the condensation of vapors and the return of this condensate to the system from which it originated. Reflux may also refer to: Duodenogastric reflux or biliary reflux; Acid indigestion, cardialgia or pyrosis, all synonyms for ...

    Medium-chain triglyceride, or MCT oil, is derived from coconut or palm kernel oil. MCTs are chains of fatty acids that the body digests and converts into energy faster than long-chain ...

  9. Consumer (food chain) - Wikipedia

    en.wikipedia.org/wiki/Consumer_(food_chain)

    Within an ecological food chain, consumers are categorized into primary consumers, secondary consumers, and tertiary consumers. [3] Primary consumers are herbivores, feeding on plants or algae. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).
