No animals get nitrogen from eating plants or other animals that contain nitrogen and plants get nitrogen from the soil by absorption through their roots as amino acids, nitrate ions, nitrite ions, or ammonium ions.
<span>The common difference between the three organisms
is the area in which they specifically live or stay in the ocean. Planktons can’t
be seen by the naked eye and they require microscopes to be detected. Planktons
usually float in the water and they cannot move on their own that’s why they
are dependent in the movement of the water.
Nektons are organisms that swim through the water and they live in different
depths in the ocean ecosystem. Nektons are composed of fish and other mammals
that propel themselves through the water.
Benthos are organisms that live in the ocean floor and many of these organisms
stay in one place by attaching themselves to rocks. This adaptation protects
them from crashing waves and drastic water movements. Other benthos are known
to burrow in the ocean floor either for food or protection.</span>
