2. Heterotroph - Wikipedia

   en.wikipedia.org/wiki/Heterotroph

   A heterotroph (/ ˈ h ɛ t ər ə ˌ t r oʊ f,-ˌ t r ɒ f /; [1] [2] from Ancient Greek ἕτερος (héteros) 'other' and τροφή (trophḗ) 'nutrition') is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are ...

3. Heterotrophic nutrition - Wikipedia

   en.wikipedia.org/wiki/Heterotrophic_nutrition

   All heterotrophs (except blood and gut parasites) have to convert solid food into soluble compounds which are capable of being absorbed (digestion). Then the soluble products of digestion for the organism are being broken down for the release of energy (respiration). All heterotrophs depend on autotrophs for their nutrition. Heterotrophic ...

4. Consumer (food chain) - Wikipedia

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

   An example is the koala, because it feeds only on eucalyptus leaves. Primary consumers that feed on many kinds of plants are called generalists. Secondary consumers are small/medium-sized carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers.

5. Heterotrophic picoplankton - Wikipedia

   en.wikipedia.org/wiki/Heterotrophic_picoplankton

   Heterotrophic picoplankton play a critical role in nutrient and carbon recycling in ecological food webs [4] by transforming and mineralizing organic matter. [7] Aquatic dissolved organic matter is one of the largest organic pools on Earth and a major part of the carbon cycle. [8]

6. Holozoa - Wikipedia

   en.wikipedia.org/wiki/Holozoa

   Holozoa (from Ancient Greek ὅλος (holos) 'whole' and ζῷον (zoion) 'animal') is a clade of organisms that includes animals and their closest single-celled relatives, but excludes fungi and all other organisms.

7. Photoheterotroph - Wikipedia

   en.wikipedia.org/wiki/Photoheterotroph

   Photoheterotrophs generate ATP using light, in one of two ways: [6] [7] they use a bacteriochlorophyll-based reaction center, or they use a bacteriorhodopsin.The chlorophyll-based mechanism is similar to that used in photosynthesis, where light excites the molecules in a reaction center and causes a flow of electrons through an electron transport chain (ETS).
