Question

In which zone can rooted plants be expected to be found attached to the seafloor? What is the name of this zone, and why are plants found there?

Answer 1

Just adding a bit on what the other person said.

Plants that are attached to the ocean surface live in the benthic zone. These plants are also found in the epipelagic zone which maxes at 200m. Plants and life need warmth, oxygen, and sunlight. At these depths, all of these are available to ocean life.

Answer 2

Hello!

The answer you're looking for is the Benthic zone:

The Benthic zone is the region at the lowest level on an ocean or lake, including the seabed. In this zone is where plants can attach themselves to the ocean floor if the water is shallow enough for the sunlight to reach them. Some plants that can be found in the Benthic zone include:

-Eel Grass
-Mangroves
-Turtle Grass
-Cattails
