Explanation:
Detailed explanation-1: -External parasites often annoy their hosts by biting, embedding, or otherwise irritating the skin. They can cause serious diseases, such as mange and scabies, which affect animals’ health and growth. Internal parasites live in the blood or tissues inside an animal’s body.
Detailed explanation-2: -Parasite life cycles involving only one host are called “direct"; those with a definitive host (where the parasite reproduces sexually) and at least one intermediate host are called “indirect". An endoparasite lives inside the host’s body; an ectoparasite lives outside, on the host’s surface.
