Answer:
C. Niche overlap is small and the carrying capacities are similar.
Explanation:
The Lotka-Volterra model is used to predicts if coexistence of two species is possible .The Lotka–Volterra models show that coexistence is more likely if niche overlap is small and the carrying capacities are similar.
Answer: Overfishing is a dangerous global issue that is often overlooked people who do not directly rely on marine wildlife for protein.
