yes
No. they are scavengers.
They are carnivores, consumers, and predators.
they eat krill and mini fish (edit) This depends on the species of hermit crab. Some of them are omnivores and herbivores, and they eat algae and debris.
The horseshoe crab is a consumer, because they use food to get energy.
depends on what kind of crab. hermit crabs are herbivores. fiddlers might though....
Crabs feed primarily off of detritus on the ocean floor. As such, they are scavengers and not herbivores, therefore they are not primary consumers.
Well yes because they are omnivores meaning they eat meat and plant.
the whooping crane eats a variety of things such as blue crab, crab, fish, minnows, plants, insects, and frogs, along with snails.
Most crabs are omnivores but prefer to eat meat such as bivalves (clams, osters, ect.), because they can assimilate more nutrients from the meat. The plants are low in nitrogen, which is an important nutrient for the crabs. However, there are a few species of crabs that are strictly herbivores.

Krills are herbivores
No, all tigers are carnivores, not herbivores.
