Following arrangement is correct from the point of view of decreasing biodiversity in angiosperms (N), fungi (F), pteridophytes (P) and algae (A).

  1. N $>$ F $>$ P $>$ A
  2. N $>$ F $>$ A $>$ P
  3. F $>$ N $>$ P $>$ A
  4. F $>$ N $>$ A $>$ P
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Biodiversity means the diversity of species of genetic variation within one species and of ecosystem angiosperms have the ability to live animals into transporting their pollen and seeds. Fungi, unlike plants and pteridophytes, are vascular plants that produce neither flowers nor seeds. Algae cannot synthesize their food and need an external source of nutrients. The order of decreasing biodiversity is N>F >A>P. Hence, the correct answer is option B,  N>F >A>P.
