Kelp are multicellular photosynthetic protists that make up kelp forests. these forests are found in the cold nutrient-rich water off the coast of california. they make up one of the most biologically productive habitats in the marine world and can grow up to 30 cm per day.

at what ocean depth would you expect to find kelp forests?

a. 0-40 m

b. 50-100 m

c. 150-300 m

d. 300-500 m

The correct answer would be A. 0-40 m.

Kelp are photosynthetic protists, thus, they require sunlight in order to perform photosynthesis which is essential for their survival.

It limits their presence up to the depth of 40 meters as the amount of available sunlight keeps on decreasing with increase in depth of the ocean.

maybe because its impossible for balloons to lift a whole entire house.

thats not a question
