Question

Competition for food, light and space is most severe in:

• A. Closely related species growing in the same area (in the same niche)
• B. Closely related species growing in different habitat
• C. Distantly related species growing in the same habitat
• D. Distantly related species growing in different habitat

Answer 1

The correct option is A Closely related species growing in the same area (in the same niche)

Competition occurs when individuals attempt to obtain a resource that is inadequate to support all the individuals seeking it. This competition mainly arises when the same species compete for the same niche, territory, or resources. Hence, competition for food, light and space is most severe in closely related species growing in the same area (in the same niche).
