question 44

Multiple Choice

The Lotka-Volterra Model relies heavily on a variable known as the competitive coefficient (α₁₂) .Which of the following statements regarding the competitive coefficient is true?

• A) The value of the competitive coefficient is constant for a given species, regardless of competitor it is being compared to
• B) If the value of α₁₂ = 0.5 for any species 1 and species 2, then the competitive effect that species 2 has on species 1 is twice the effect species 1 has intraspecifically
• C) If the value ofα₁₂ = 0.5 for any species 1 and species 2, then the competitive effect that species 2 has on species 1 is half the effect species 1 has intraspecifically
• D) If the value of α₁₂ = 0.5 for any species 1 and species 2, then the competitive effect that species 1 has on species 2 is half the effect species 2 has intraspecifically
