Question

Which of the following is not a parasitic adaptation?

• A. Loss of unnecessary sense organs
• B. Absence of adhesive organs or suckers
• C. Loss of digestive system
• D. High reproductive capacity

Hint:

Adaptations like adhesive organs enhance parasitic efficiency.

Answer 1

The Correct Option is B

Parasitic adaptations are specialized features that enable parasites to survive and thrive in or on their hosts. These typically include:

(A) Loss of unnecessary sense organs – Correct adaptation: Parasites often reduce or lose sense organs (e.g., eyes) as they rely on the host.

(B) Absence of adhesive organs or suckers – Not a parasitic adaptation: Most parasites require suckers, hooks, or adhesive organs (e.g., tapeworms, leeches) to attach to hosts.

(C) Loss of digestive system – Correct adaptation: Some parasites (e.g., tapeworms) absorb nutrients directly and lack a digestive system.

(D) High reproductive capacity – Correct adaptation: Parasites often produce many offspring to ensure transmission.

The correct answer is (B), as the absence of attachment structures would hinder parasitic survival.
