Answer:

Option a is the correct answer

Planktons

• Water covers 71% of the planet. Water can be found in rivers, ponds, lakes, the ocean, etc. The community in an area that interacts with both the environment and one another is called an ecosystem.
• Aquatic organisms are living things that exist in bodies of water and are dependent on water to survive. Oceans, lakes, and rivers all have aquatic ecosystems. There are several strata, including the littoral, limnetic, profundal, and benthic.

Explanation:

• Planktos, which means wanderer, is the root of the term plankton. These are not autonomous swimmers. They are carried by water currents, tides, etc.
• Plankton can be found in the upper portion of marine aquatic habitats. These top water floaters are passive.
• Nektons, in contrast to Planktons, are aquatic creatures capable of unrestricted swimming because the term "nekton" implies "to swim." These people can swim actively and are unaffected by water currents. These can be vertebrates, squids, or crabs, but they are not found in the top portion of the sea. "Ernst Haeckel" came up with the phrase.
