Maggots consume dead or decaying organisms so they are classified as a decomposer.
Decomposition is a process by which organic substances, like leaves or dead animals, are broken down into simpler matter.
A lot of different types of organisms, called the decomposers, will consume the organic substances and continue an essential part of the nutrient cycle. These organisms can be both bacteria, fungi but can also be insects.
This is important for recycling the organic matter that occupies space in the biosphere and that way, continues the movement of energy and matter in ecosystems.
The most prominent example of carbon fixation is photosynthesis
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Answer: Decomposers plan an important role in the biogeochemical cycling for nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.
