Advantages of modeling are that a model is what three thing? Predictive, can be tested, and can be adjusted.
What model predicts that species coexist when intraspecific competition is stronger than interspecific competition? The Lotka – Volterra model
The process of evolution toward niche divergence in the face of competition is known as what? Character displacement
What species occur in separate locations? Allopatric species
What species occur in the same region? Sympatric species
