It's a cave, it had to be diged by water so somewhere there are probably
fish and aquatic ecosystem

Also there are lot of animals that hide in a cave and get out to eat, orcs
who don't want to get out just have to hunt them. These may be lizards,
insects, bats (as you thought of), big mammals


They could breed some animals like lizards that eat insects


There could have some fossil combustible that they would burn and from which
they would get the necessary light to make some agriculture



But in a conworld you can do something:

If the montain in which the orcs live contains radioactive ressources, there
could have plants that evolved to not only support but also use the
radioactivity as source of energy

The beta(betha?) particles (that can be stoped by paper and so are the less
powerful) could probably be used to produce energy with an organism adapted
to it
