Consumers that eat plants are called primary consumers or herbivores. Consumers that eat other animals are secondary consumers or carnivores. Crustaceans are animals with jointed legs, a pair of antennae and an outer hard exoskeleton. The best known marine crustaceans are crabs and lobsters.
In this regard, what type of consumer is a crustacean?
Primary Consumers These animals, small or large, eat the primary producers. Ducks, tadpoles, mayfly nymphs, and small crustaceans are all considered primary consumers. The most populous of the primary consumers are the zooplankton. These tiny animal-like organisms consume phytoplankton in large quantities.
Additionally, are crustaceans producers? They are a vital food web link between primary producers (algae and aquatic weeds) and higher trophic levels. Crustaceans obtain food as detritivores, herbivores, omnivores, and carnivores, and they range in size from minute zooplankton only 0.1 mm long up to giant crayfish at 400 mm.
In this way, what do crustaceans eat?
Smaller aquatic crustaceans eat microscopic organisms, algae and plankton, while their larger counterparts enjoy diets of snails, plants and the larvae and eggs of other marine life. Large lobsters and crabs survive on fish and other crustaceans with a predatory nature that involves stalking their prey.
