Sea urchins are classified as benthic organisms, meaning they live on or near the ocean floor. They are not plankton, which are typically small, drifting organisms in the water column, nor are they nekton, which are actively swimming animals like fish. Sea urchins play an important role in their ecosystem by grazing on algae and contributing to the structure of marine habitats.
A sea urchin is classified as benthos. Benthos refers to organisms that live on or near the bottom of a body of water, and sea urchins typically inhabit the ocean floor, often among rocks or coral. In contrast, plankton are free-floating organisms, and nekton are active swimmers.
Sea otter are nekton and plankton; they can float and swim.
nekton
Plankton aren't turtules and plankton aren't turtles.
No, sea stars are benthic organisms. Plankton means drifter, they float around for their whole lives.
benthos - it lives on the sea bed and "swims" occassionally.
Zooplankton (pronounced ZO A PLANKTON) is plankton
A sea urchin is a consumer because it feeds on algae, plankton, and decaying matter by using its tube feet and spines to gather food particles from the water and its surroundings.
The deepest part of the "benthic zone" for aqueous ecology is the "hadal" zone (6000 meters or more beneath the surface). It is also known as the hadopelagic or "trench zone" of deep-sea organisms.
Dolphins are nekton because they actively swim and catch their food.
The classification of a Sea Urchin is Echinoidea
No, a sea urchin is not a necton. Necton refers to free-swimming aquatic animals that can actively move through the water column, such as fish and squid. Sea urchins are benthic organisms, meaning they primarily inhabit the ocean floor and do not swim freely in the water. Instead, they move slowly by using their tube feet and spines.
