Are the most numerous unicellular algae in the oceans.
amoebas
golden algae
diatoms
none of the above

The correct answer will be diatoms.

Explanation:

Diatoms are photosynthesizing micro-algae found in both marine and freshwater usually hard and rough in appearance due to deposition of silica in their cell walls.

They live in both photic and planktic region of the ocean and in both unicellular to colonial forms and form the major part of the planktons.

Their large number of species counts for about 20,000 and new species being discovered every year and their reproduction through simple cell division makes the most numerous unicellular algae in the oceans

Thus, diatoms is the correct answer.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
