Question:

Read the given paragraph and answer the given question :

Parasitism has evolved in many taxonomic groups from plants to higher vertebrates. Many parasites have evolved to be host specific in such a way that both host and the parasite tend to co-evolve. In accordance with their life styles, parasite evolve special adaptations and complex life cycle.

Match List -I with List - II.

List - I List - II
(A) Cuckoo and Crow (I) Ectoparasite
(B) Copepods (II) Commensal Organism
(C) Plasmodium (III) Brood Parasitism
(D) Orchids and Mango tree (IV) Endoparasite

Choose the correct answer from the options given below:

Options:

(A)-(III), (B)-(II), (C)-(I), (D)-(IV)

(A)-(III), (B)-(I), (C)-(IV), (D)-(II)

(A)-(II), (B)-(I), (C)-(III), (D)-(IV)

(A)-(I), (B)-(III), (C)-(IV), (D)-(II)

Correct Answer:

(A)-(III), (B)-(I), (C)-(IV), (D)-(II)

Explanation:

 The correct answer is Option (2) –(A)-(III), (B)-(I), (C)-(IV), (D)-(II)


List - I List - II
(A) Cuckoo and Crow (III) Brood Parasitism
(B) Copepods (I) Ectoparasite
(C) Plasmodium (IV) Endoparasite
(D) Orchids and Mango tree (II) Commensal Organism

Here's an explanation of the matching between List I and List II:

(A) Cuckoo and Crow - (III) Brood Parasitism

  • Cuckoos are known for practicing brood parasitism, where they lay their eggs in the nests of other bird species, such as crows, and let the host birds raise their young.

(B) Copepods - (I) Ectoparasite

  • Copepods are small aquatic organisms that often act as ectoparasites, attaching themselves to the external surfaces of other organisms, like fish, to feed on their tissues or blood.

(C) Plasmodium - (IV) Endoparasite

  • Plasmodium is a parasite responsible for causing malaria in humans. It is an endoparasite because it resides inside the host's red blood cells.

(D) Orchids and Mango tree - (II) Commensal Organism

  • Orchids and mango trees are examples of commensal organisms. Commensalism is a type of symbiotic relationship where one organism benefits, and the other neither benefits nor is harmed. In this case, orchids may grow on the branches of mango trees, using them as a support structure, without causing harm to the mango tree.

These associations describe the ecological relationships between these organisms and their interactions with other species.
