Question

use the text to compare and contrast a larva and a pupa. the larva and the pupa represent two stages of an insects life. after an egg hatches, an insect enters the first active phase of life and becomes a larva. the larvas main job is to feed and store energy. the pupa is the next stage of an insects life. although the larva feeds constantly, the pupa usually does not feed and appears motionless. unless it lives inside a stem or a leaf, the pupa builds a protective outer shell called a cocoon. inside the cocoon, the pupa transforms from a soft, worm - like creature into a new physical form, such as a butterfly or a moth. unlike the pupa, a larva doesnt build a cocoon and remain inside. instead, the larva is busy eating—and often destroying—agricultural crops.

Explanation:

• For "Is in the first active stage of life": According to the text, after an egg hatches, an insect becomes a larva (the first active phase), so this applies to "A larva".
• For "Doesn't feed": The text states "the pupa usually does not feed", so this applies to "A pupa".
• For "Is usually enclosed in a cocoon": The text says "the pupa builds a protective outer shell called a cocoon", so this applies to "A pupa".
• For "Can damage crops": The text mentions "the larva is busy eating—and often destroying—agricultural crops", so this applies to "A larva".

Answer:

A larva: Is in the first active stage of life, Can damage crops
A pupa: Doesn't feed, Is usually enclosed in a cocoon
