Which of the following is sedentary in adult and active in larval stage?
Correct answer: A. Sponge
- A. Sponge
- B. Leech
- C. Salamander
- D. Grasshopper
Explanation
The correct answer is Sponge. Sponges have a sedentary adult stage where they are attached to a substratum, while their larval stages (Amphiblastula and Parenchymula) are free-living and active. Leeches, salamanders, and grasshoppers are all active in both their adult and larval stages, making them incorrect choices for this question.
