Hawks, herons, owls, ospreys, (maybe eagles), wolves, various types of snakes, foxes, coyotes, bobcats, domestic cats, and mountain lions will prey upon mice.
If by marsh, you mean the environment in general, then the animal that eats that is a decomposer. Decomposers breakdown bottom level decomposing materials like dead plant and animal material and turn it into renewable energy.

A mouse is a small animal that eats grains and can be preyed upon by snakes. This relationship forms part of the food chain where the mouse is a herbivore consuming grains, which in turn becomes a food source for snakes, which are carnivores.
Secondary consumers like cheetahs eat deer or elk while a snake eats a mouse that eats grass. A mouse or a deer is a primary consumer while the things that eats that is a secondary consumer
The western harvest mouse is primarily considered an herbivore, as its diet mainly consists of seeds, grains, and fruits. However, it may occasionally consume insects, which gives it some omnivorous traits. Overall, while it primarily eats plant material, it can supplement its diet with small amounts of animal protein.
it is almost the last but a different animal eats it in the lake,pond and marsh.
