As a soft guide, however, the numbers of identified species as of 2004 can be broken down as follows:
* 287,655 plants, including:
o 15,000 mosses,
o 13,025 ferns,
o 980 gymnosperms,
o 199,350 dicotyledons,
o 59,300 monocotyledons;
* 74,000-120,000 fungi[1];
* 10,000 lichens;
* 1,250,000 animals, including:
o 1,190,200 invertebrates:

+ 29,300 fish,
+ 5,743 amphibians,
+ 8,240 reptiles,
+ 9,934 birds,

However the total number of species for some phyla may be much higher:
* 5-10 million bacteria
* 1.5 million fungi;
