Yes, animals are consumers plants are producers.
In biological circles, the producers (autotrophs) are plants and green algae, which capture energy from sunlight to produce their own food, or in other words capture carbon into the food chain. By contrast, crabs, crayfish, and lobster eat other organisms (both plants and animals) and are thus variously classified as omnivorous, often predatory/carnivorous, or heterotrophic; as such they are considered consumers.
