Question

Arrange the four stages in the life cycle of mosquito from the first stage to the last stage.
A. Adult
B. Larva
C. Egg
D. Pupa
Choose the correct answer from the options given below:

• A. A, B, C, D
• B. A, C, B, D
• C. B, A, D, C
• D. C, B, D, A

Hint:

Remember that the first three stages of a mosquito's life (Egg, Larva, Pupa) are aquatic. This is why controlling stagnant water is the most effective way to prevent mosquito breeding.

Answer 1

The Correct Option is D

Step 1: Recall the complete metamorphosis cycle of insects like mosquitoes. Step 1: Mosquitoes undergo complete metamorphosis, which means their life cycle has four distinct stages.
Step 2: List the stages in their natural order.
Step 2:

(C) Egg: The life cycle begins when a female mosquito lays eggs on or near water.
(B) Larva: The eggs hatch into larvae (often called "wrigglers"), which live in the water and breathe at the surface.
(D) Pupa: The larva develops into a pupa (often called a "tumbler"), which also lives in the water but does not feed.
(A) Adult: The adult mosquito emerges from the pupal case and flies off.
Step 3: Form the correct sequence.
Step 3: The correct life cycle sequence is Egg \(\rightarrow\) Larva \(\rightarrow\) Pupa \(\rightarrow\) Adult, which corresponds to C \(\rightarrow\) B \(\rightarrow\) D \(\rightarrow\) A.
