Aquatic Biome- The Euphotic Zone

By: Nicole Pitchford

Uppermost layer of all the worlds oceans. (appx. 50-660 ft deep)

Called “sunlit zone” Temperature ranges from 104-27 degrees

Fahrenheit.

Location

Food ChainDiatoms

Shrimp

Ocean Fish

Tuna

Marlin

This is an aquatic biome. Saltwater The plants in this zone create 90% of the

Earths oxygen. Largest amount of sea life lives here (90%),

but it is the smallest size in volume. Sea life from coral reefs to Orka sharks thrive

in this ocean level.

Type of Habitat

Fishing grounds/food Recreation- surfing, scuba diving, fishing etc.

Human Use

Fishing nets that are drug across the sea floor, dynamiting coral reefs, over fishing popular species, and poising harm the biome.

Pollution from humans like fertilizers and household chemicals harm multiple parts of the aquatic biome.

Trash and oil from boats pollute water and animals in the ocean.

Threats

There are no real ‘subbiomes’ within the Euphotic layer, however, there are many different ecosystems including:

Rocky/sandy ocean floor Coral Reefs Kelp Forests
