Photosynthetic plants are the primary producers of the fixed carbon compounds that virtually all animals eat. Therefore, in some strict sense of the word parasite, all non-photosynthetic organisms are parasites of photosynthetic organisms. Photosynthetic organisms are parasites of the sun's energy. Further discussion belongs under thermodynamics, or under semantics of the word "parasite". (However some bacteria grow using mineral substrates thereby creating biomass that is not of photosynthetic origin. I believe that non-photosynthetic biomass is not a significant proportion of the photosynthetic biomass but I do not know of an estimate of the rate or abundance of non-photosynthetic biomass.) |

Number of Species
This page should say how many species are in the phylum. --Savant13 20:32, 21 December 2006 (UTC)

Parasites
So should all animals be defined as parasites, as, like their ancestors the fungi, they are living off of other organisms?
yes, parasites
Photosynthetic plants are the primary producers of the fixed carbon compounds that virtually all animals eat. Therefore, in some strict sense of the word parasite, all non-photosynthetic organisms are parasites of photosynthetic organisms. Photosynthetic organisms are parasites of the sun's energy. Further discussion belongs under thermodynamics, or under semantics of the word "parasite". (However some bacteria grow using mineral substrates thereby creating biomass that is not of photosynthetic origin. I believe that non-photosynthetic biomass is not a significant proportion of the photosynthetic biomass but I do not know of an estimate of the rate or abundance of non-photosynthetic biomass.)
Note also that fungi are not the ancestors of animals; animals and fungi are thought to have a common ancestor.
