- Bthey are sensitive to the phases of moon
- Cthe desert insects eat away flowers during day time
- Dthe desert insects are active during night timeCorrect
Explanation
The correct answer is D because pollination in the desert is closely linked to the activity patterns of local insects and animals. In harsh desert environments, many insects and pollinators like moths and bats are nocturnal to avoid the extreme heat and dehydration of the day. Plants have adapted to this by blooming at night to coincide with the time when these pollinators are most active, ensuring successful reproduction while minimizing water loss from the flowers.
