This map shows the eight biomes of the world. The orange area is tundra, purple
is taiga, green is grassland, black is temperate forest, yellow is desert, blue is tropical rain forest, brown is chaparral and the white is ocean.

Climate Changes with Latitude
Places located at high latitudes (far from the equator) receive less sunlight
than places at low latitudes (close to the equator). The amount of sunlight
and the amount of precipitation affects the types of plants and animals that
can live in a place. The collection of all the living things in a place, as
well as the non-living resources, is called an ecosystem or biome. Listed below
are the types of ecosystems that exist in the climates of different latitudes.
The most sunlight is received at the equator of our planet, making this area
very warm. The types of ecosystems that develop in this warm environment are:
- Rainforests: As the name suggests,
rainforests receive a lot of rain. The temperature stays warm in the rainforest
all year long.
- Savanna: This ecosystem has a wet season and a very dry season.
- Deserts: Deserts receive less rainfall
than other tropical ecosystems but are just as warm.
The area between the warm tropics and the chilly poles is called the mid latitudes.
Climates in this zone are affected by both warm, tropical air moving towards
the poles and cold, polar air moving towards the equator.
- Chaparrel: This ecosystem has wet-winters and dry-summers.
- Grasslands: This ecosystem is typically
found on the dry interior of continents.
- Temperate forest: A moist climate
allows leafy deciduous trees to thrive.
High latitudes receive the least sunlight, creating cold climates.
- Taiga: The forests of the taiga ecosystem survive despite long and very
cold winters. Summers are short and still quite cool.
- Tundra: Ocean winds in arctic
coastal areas keep the temperatures from being as severe as interior regions.
A long, chilly winter season is followed by a mild season.
