Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. PSQR.
- The paragraph begins by introducing the deadwood beetles and their role in recycling the nutrients of woodlands.
- This is followed by the description of how they work alongside other organisms to break down dead wood and return the nutrients back to the soil.
- The next sentence talks about how some deadwood beetles restrict population growth of potential pests by being predators or parasitoids to other insect species.
- Finally, the paragraph ends by mentioning how some deadwood beetles have been recently found to be pollinators.
Thus, the coherent paragraph is:
Many deadwood beetle species recycle the nutrients of woodlands. Working alongside fungi, bacteria and other invertebrates, they break down dead wood and return the nutrients back to the soil. Some deadwood beetles are predators or parasitoids to other insect species and restrict population growth of potential pests. Others have recently been found to be pollinators.
