Ocean:
Definition: The ocean biome is the largest and most diverse ecosystem on
Earth, covering about 70% of the planet's surface. It is characterized by
saltwater and includes various zones such as the intertidal, pelagic, and
abyssal zones. The ocean biome supports a wide array of marine life,
ranging from microscopic phytoplankton to large whales.
Rainforest:
Definition: The rainforest biome is characterized by high annual rainfall,
lush vegetation, and high species diversity. It is typically found in tropical
regions near the equator. Rainforests consist of multiple layers, including
the emergent, canopy, understory, and forest floor, each providing unique
habitats for a myriad of plant and animal species.
Tundra:
Definition: The tundra biome is characterized by low temperatures, short
growing seasons, and a lack of trees. It is found in Arctic and alpine
regions, where the subsoil is often permanently frozen (permafrost).
Tundra vegetation consists mainly of grasses, mosses, lichens, and hardy
shrubs, and it is home to animals adapted to harsh cold conditions .
Savanna:
Definition: The savanna biome is a grassland ecosystem with scattered
trees and is typically found in tropical and subtropical regions. Savannas
are characterized by a distinct wet and dry season, supporting a mix of
grasses and shrubs. Large herbivores, such as zebras and giraffes, coexist
with carnivores like lions and cheetahs in this biome.
Desert:
Definition: The desert biome is characterized by low precipitation levels
and extreme temperature fluctuations between day and night. Deserts can
be hot or cold and are often marked by arid landscapes with sparse
vegetation. Plant and animal life in deserts are adapted to conserve water,
and many species are nocturnal to avoid the intense daytime heat.
