<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>

<span>Since you left off the choices, I have to just present the facts of what occurs first in the nerve impusle. The first thing that will is happen is the sodium ios will move to the inside of the nueron. The second step is the potassium ions will move to the inside of the neuron. After those move into the nueron, calcium will then move into the nueron. Both the sodium and potassium have 1 postive charge. While the calcium ion has 2 positive charges. </span>
<span>the definition: Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. Adaptations are the result of evolution. Evolution is a change in a species over long periods of time. The Answer is D. Protective over young cubs</span>
