  2. Autotroph - Wikipedia

    en.wikipedia.org/wiki/Autotroph

    The first autotrophic organisms likely evolved early in the Archean but proliferated across Earth's Great Oxidation Event with an increase to the rate of oxygenic photosynthesis by cyanobacteria. [8] Photoautotrophs evolved from heterotrophic bacteria by developing photosynthesis. The earliest photosynthetic bacteria used hydrogen sulphide.

  3. Photoautotroph - Wikipedia

    en.wikipedia.org/wiki/Photoautotroph

    Cyanobacteria is the only prokaryotic group that performs oxygenic photosynthesis. Anoxygenic photosynthetic bacteria use PSI- and PSII-like photosystems, which are pigment protein complexes for capturing light. [5] Both of these photosystems use bacteriochlorophyll. There are multiple hypotheses for how oxygenic photosynthesis evolved.

  4. Ecosystem respiration - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_respiration

    Cellular respiration is the overall relationship between autotrophs and heterotrophs.Autotrophs are organisms that produce their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend on autotrophs for nutrition.

  5. Primary nutritional groups - Wikipedia

    en.wikipedia.org/wiki/Primary_nutritional_groups

    Primary nutritional groups are groups of organisms, divided in relation to the nutrition mode according to the sources of energy and carbon, needed for living, growth and reproduction. The sources of energy can be light or chemical compounds; the sources of carbon can be of organic or inorganic origin.

  6. Energy flow (ecology) - Wikipedia

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

    The first step in energetics is photosynthesis, where in water and carbon dioxide from the air are taken in with energy from the sun, and are converted into oxygen and glucose. [7] Cellular respiration is the reverse reaction, wherein oxygen and sugar are taken in and release energy as they are converted back into carbon dioxide and water.

  7. Carbon source (biology) - Wikipedia

    en.wikipedia.org/wiki/Carbon_source_(biology)

    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.Autotrophs produce complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, [1] generally using energy from light or inorganic chemical reactions.

  8. Maxine is usually so happy and smiley, so it's clear that the outfit dad put on her is what's making her so upset. I cracked up when he asked if she liked it, and she looked at him like he was ...

  9. Phytoplankton - Wikipedia

    en.wikipedia.org/wiki/Phytoplankton

    Phytoplankton (/ ˌ f aɪ t oʊ ˈ p l æ ŋ k t ə n /) are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems.The name comes from the Greek words φυτόν (phyton), meaning 'plant', and πλαγκτός (planktos), meaning 'wanderer' or 'drifter'.
