Do mosquitoes have any significant role to play in the ecosystem? In general what living beings have almost no role to play in the ecosystem?

Also, are all "plants" types important to an ecosystem because they are autotrophs (apart from some archea bacteria)?

The basic ecosystem (for me) is: herbivore, carnivore and omnivore. Mosquitoes - do they help in pollination? (like insects do).

If answer is no then one can also argue that even humans are not required, but I'd say the "brain power" we've got changes the answer to "yes" (imo).

Just a thought, (consider) for female aedes mosquito, the virus apparently lives in her, so in a way the mosquito is helping the virus, does it count as a role? At the same time viruses are neither living nor dead so do they really need a place to "live", also if the mosquitoes suddenly vanish can the virus "live" somewhere else, is there any problem here?

Mosquitoes are very important.

Mosquitoes actually play a role in pollination of many plants.  As well mosquito larva are an important food source for many fish, frogs, and so forth.. and adult mosquitoes are important food sources for birds, bats, dragonflies, and many other animals.

Mosquitoes are insects by the way.

I suppose some total parasites might not have beneficial roles.. unless you consider that they help keep population levels slightly lower.. such as the fact that some animals are weakened by parasites and die.
