Q. Crop plants grown in monoculture are :
A) low in yield
B) free from intraspecific competition
C) characterised by poor root system
D) highly prone to pests
Explanation
[Solution from source] Large areas of one genetically uniform crop give a pest or pathogen that attacks it an unlimited food supply, so monocultures are highly prone to pest outbreaks. They are not free from intraspecific competition, since all plants are the same species competing for the same resources. Answer (4).
