Question

In accordance to their life styles ________ have evolved characters like loss of unnecessary sense organs, suckers, loss of digestive system and high reproductive capacity.

• A. endoparasites
• B. ectoparasites
• C. hosts
• D. brood parasites

Hint:

Think of parasites living inside the body, such as tapeworms.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
Parasites show special adaptations suited to their way of life.

Step 2: Endoparasites
Endoparasites live inside the host where food is already digested. So they lose unnecessary sense organs and often the digestive system.

Step 3: Other features
They have suckers and hooks to hold on to host tissue and produce very large numbers of eggs, because the chance of reaching a new host is small.

Final Answer:
These characters are seen in endoparasites. \[ \boxed{\text{(A) }\text{endoparasites}} \]
