The correct options are
B Saprozoic - Beatle
C Parasitic - vulture
D Decomposer - tick
Carnivores eat other animals. The anteater eats ants and hence is a carnivore. Scavengers eat dead bodies, e.g. vultures. Saprozoic nutrition involves absorbing digested nutrients from dead bodies, for example, fungi. Parasites depend organisms for food but do not kill them, an example is the tick.
