The Aquatic Biome

This includes all water bodies on the earth’s surface. Aquatic biomes are grouped into two,
Freshwater Biomes (lakes and ponds, rivers and streams, wetlands) and Marine Biomes
(oceans, coral reefs and estuaries). These biomes make up about 73% of the total
earth’s surface.

Life forms in these waters depend on the abiotic factors such as sunlight entering the waters,
temperature, pressure, salt content and so on. Water biomes with lots of light tend to have
more flora (plant) diversity, and the growth of algae and plankton is more. Small water bodies
that freeze during the cold seasons, or dry out in the dry and hot seasons tend to have less
diversity.

fishes, sharks and tuna and sea birds. Examples of animals
in freshwater biomes include salmon, tilapia worms,
water-surface insects and crabs.

Aquatic biomes are very important because apart from being
home to millions of water animals, they also form the basis
of the water cycle and help with atmospheric moisture, cloud
formation and precipitation. One example of a marine biome
is the Great Barrier Reef (a coral reef system) of Australia.

An example of a fresh water biome is the Amazon river in Brazil.
