Answer 1

The correct option is D Predator is an organism that catches and kills other organism for food.

Predator is an organism that hunts, catches, kills, and eats other animals. Parasitism is a type of symbiosis where one organism (the parasite) benefits and the other (the host) is harmed. A host is an organism that harbors a parasite, or a mutual or commensal symbiont, providing nourishment and shelter. Amensalism is an association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected.
