What is the principle that teaches us that two species cannot coexist in the exact same niche in the same habitat.This is because species with same niches have comparable requirements, which implies they would fight for the same resources.
What is the difference between competitive exclusion and resource partitioning?
Discuss competition between species, the competitive exclusion principle, and the phenomenon of niche or resource partitioning. How do they compare and/or contrast?
