Answer 1

Answer: hey mate!!!

a) Dinoflagellates

The dinoflagellates are a large group of flagellate protists. About half are photosynthetic, the rest are mostly heterotroph predators of other protists. The ones which are photosynthetic are sometimes loosely called 'algae'; the one which are predators are sometimes loosely called 'protozoa'.  They have been classified as an order, a class and a phylum by different authors. Active research is being done on their relationships.  Most are marine plankton, but they are common in fresh water habitats as well. Their populations are distributed depending on temperature, salinity, or depth. The group includes many symbionts and bioluminescent species.  About 1,555 species of free-living marine dinoflagellates are currently described. The latest estimates suggest a total of 2,294 living dinoflagellate species, which includes marine, freshwater and parasitic dinoflagellates.

sorry i know about this only i hope it helps a little bit

DINOFLAGELLATES:-

The dinoflagellates are a large group of flagellate protists. About half are photosynthetic, the rest are mostly heterotroph predators of other protists. The ones which are photosynthetic are sometimes loosely called 'algae'; the one which are predators are sometimes loosely called 'protozoa'.

DIATOMS:-

Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric. A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule.

SLIME MOLDS:-

Slime mold or slime mould is an informal name given to several kinds of unrelated eukaryotic organisms that can live freely as single cells, but can aggregate together to form multicellular reproductive structures. Slime molds were formerly classified as fungi but are no longer considered part of that kingdom.
