The planet Earth

*Biomes* are climatically and geographically defined as similar climatic
conditions on the Earth, such as communities of plants, animals, and soil
organisms,^[1] and are often referred to as ecosystems. Some parts of the
earth have more or less the same kind of abiotic and biotic factors spread
over a large area, creating a typical ecosystem over that area. Such major
ecosystems are termed as biomes. Biomes are defined by factors such as
plant structures (such as trees, shrubs, and grasses), leaf types (such as
broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and
climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or
historical similarities. Biomes are often identified with particular
patterns of ecological succession and climax vegetation (quasiequilibrium
state of the local ecosystem). An ecosystem has many biotopes and a biome
is a major habitat type. A major habitat type, however, is a compromise, as
it has an intrinsic inhomogeneity. Some examples of habitats are ponds,
trees, streams, creeks, under rocks and burrows in the sand or soil.

The biodiversity characteristic of each extinction, especially the
diversity of fauna and subdominant plant forms, is a function of abiotic
factors and the biomass productivity of the dominant vegetation. In
terrestrial biomes, species diversity tends to correlate positively with
net primary productivity, moisture availability, and temperature.^[2]

Ecoregions are grouped into both biomes and ecozones.

A fundamental classification of biomes are:

1. Terrestrial (land) biomes
2. Aquatic biomes (including freshwater biomes and marine biomes)

Biomes are often known in English
