    Same animals of same niche
  • C
    Different animals of different niche
  • D
    Same animals of different niche
✓

Answer

Correct option: B.
Same animals of same niche
b
Since, same animals of a niche have the similar requirements of food, light, water, space, shelter and mate, etc, so intraspecific competition (between animals of same species) is more acute than interspecific, when different animals have different requirements and adaptations ($i.e.,$ different niche).In same niche, there will always a competition but it is more severe, when similar animal species are present and less, when different animals are there with a few similar needs.
