A is the predator, and B is the prey. Predators are carnivores that stalk and hunt their prey, and a predator is an animal that seeks other animals, while the prey is the animal that the predator is hunting. These two groups of species are mandatory for maintaining an ecological balance on the earth.
The predator is quite dependent on prey for its basic living. Some of the predator's attributes include speed, strength, camouflage, and a keen sense of smell, sight, and hearing. On the other hand, the prey are typically herbivores that do not consume other animals but sustain their life by eating plants and small insects.
Prey tries to evade the predator by utilizing their speed, camouflage, and a good sense of smell, sight, and hearing. Some common examples of predators include lions, tigers, sharks, eagles, and alligators. Some common examples of prey include cow, deer, rabbit, and mice.
