These different habitats might even be in the same geographical location or area. That is, one insect might be living in or on the surface of the water, and the other living in the soil or the tree. Due to this effect, the insects are unlikely to meet and reproduce.

What are the differences in their hard parts, distribution, reproduction among phytoplankton of cyanobacteria, diatom, coccolith
Margarita [4]

Answer:

Explanation:

DIFFERENCES BETWEEN HARD BODY PARTS.

•Cyanobacteria have calcified sheaths.

• Diatoms have hard but porous cell wall.

• Coccolithophores have hard body parts.

• Silicoflagellates skeleton is composed of opaline silica.

• Dinoflagellates do not have hard body parts

• Green algae - no hard body parts.

• Brown algae - no hard body parts.

DIFFERENCES BETWEEN DISTRIBUTION

• Cyanobacteria are found almost in every terrestrial habitat on planet.

• Diatoms are found in oceans, freshwater, soil and damp.

• Coccolithophores are exclusively marine.

• Silicoflagellates are found in marine environment.

• Dinoflagellates are both freshwater and marine.

• Green algae grow on objects that do not move such as substrate, rock.

• Brown algae - wide distribution from tropical to polar zones.

DIFFERENCES BETWEEN REPRODUCTION.

• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.

• Diatom - asexually by cell division through mitosis.

• Coccolithophores - asexually by binary fission.

• Silicoflagellates - asexually

• Dinoflagellates - asexually

• Green algae - sexually or asexually by cell division, fragmentation, spore formation.

• Brown algae - sexually and asexually.
