Question

Plankton is _____.
A. A group of important plants.
B. known to most people.
C. One of the major diets of sea animals.
D. A form of sea life balance.
E. A form of disturbance to sea life.

Answer 1

Hint Victor Hensen coined the term plankton in 1887, derived from the Greek adjective meaning errant, and by extension, wanderer or drifter. While some forms are capable of independent movement and can swim hundreds of meters vertically in a single day (a behavior known as diel vertical migration), their horizontal position is primarily determined by the surrounding water movement, and their horizontal position is primarily determined by the surrounding water movement.

Complete answer: Plankton is a diverse group of organisms that live in water (or air) and are unable to swim against the current (or wind). Plankters are the individual organisms that makeup plankton. Many small and large aquatic organisms, such as bivalves, fish, and whales, rely on them for food in the ocean.
Bacteria, archaea, algae, protozoa, and drifting or floating animals make up marine plankton, which lives in the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton is similar to marine plankton, but it can only be found in lakes and rivers.
Although plankton is commonly associated with water, there are also airborne versions, known as aeroplankton, that spend part of their lives drifting through the atmosphere. Plant spores, pollen, and wind-scattered seeds, as well as microorganisms blown into the air by terrestrial dust storms and oceanic plankton blown into the air by sea spray, are all examples.

Thus, the answer is option C: one of the major diets of sea animals.

Note: Plankton includes organisms of all sizes, including large organisms like jellyfish, even though many planktonic species are microscopic. The ecological niche and level of motility of plankton are more important than any phylogenetic or taxonomic classification. The term technically excludes organisms that live on the water's surface, which are referred to as pleuston or those that swim actively in the water, which is called nekton.
