Question
1. Define and distinguish between a functional response and a numerical response. 2. What is an 'isocline'? Draw and identify prey and predator isoclines on a phase diagram of prey and predator population size for the basic Lotka-Volterra predation model (i.e., NOT competition). Identify the joint equilibrium. Any nudge of the populations will produce stable limit cycles. For each such a situation, show using thin arrows for the change in each species numbers on each side of their isoclines. Use fat arrows to show the joint movement of predator and prey numbers.Explanation / Answer
Functional response: here we can consider consumer's in take of food as a function of food density. It is related to ecology.
Numerical response: this is also related to ecology in which the change in predator density as a function of change in prey density.
FiffercDif between functional response and numerical response:
In case of functional response we can measure the number of prey killed per predator as the prey density changes. This is directly proportional to the individual response.
In case of numerical response can measure the number of predator as prey density changes. Here we can see the predator density can be increase by two ways as reproduction and immigration .
