Inspite of interspecific competition in nature, which mechanism the competing species might have evolved for their survival? (NEET 2021)

Answer: (C) Resource partitioning. Answer: (C) Resource partitioning.

  1. A.Mutualism
  2. B.Predation
  3. C.Resource partitioning✓
  4. D.Competitive release

Correct Answer

(C) Resource partitioning

Solution & Explanation

Answer: (C) Resource partitioning. Solution: Species facing interspecific competition may evolve mechanisms that promote co-existence rather than exclusion. One such mechanism is resource partitioning, where competing species avoid competition by choosing different times for feeding or different foraging patterns (e.g., MacArthur's warblers). Mutualism and predation are different interactions; competitive release is the range expansion of a species when its competitor is removed, not a survival mechanism the competing species evolves. NCERT: Ch 11, p.199, lines 36-41 — "they point out that species facing competition might evolve mechanisms that promote co-existence rather than exclusion. One such mechanism is ‘resource partitioning’."
