- The lotka-volterra equation that describes rate of change in the predator population doesn't include intrisic rate for predators. How does it accomodate for growth in predators if the rate is missing?Use the following information to answer the next question. Predator-prey population cycles prey predator Time Сорy Look Up Share... In the above graph, the points A, B, C, and D represent the following events, in random oraer. 1. Reduction in predator population 2. Reduction in prey population 3. Increase in predator population 4. Increase in prey population The correct order for listing the events represented by A, B, C, and D is » and NumberCompetition between insect-eating bats that are active at night and purple martins (an insectivorous bird) that are active primarily during the day is most likely an example of...

Mountain lion Snake Hawk Frog Rabbit Cricket Deer Mouse Trees Grass O Interspecific competitors O Intraspecific competitors O Predator - prey Both interspecific competitors and predator-prey O Both intraspecific competitors and predator-preyDefine predation. How does the predator-prey relationship differ from the parasite-host relationship? Why is the evolutionary race be-tween predator and prey one that the predator cannot afford to win?
- Think about a predator-prey system that perfectly follows Lotka-Volterra dynamics. The search efficiency parameter (a) represents how quickly the predator finds and kills its prey. What would happen if most the predator population had a parasite that made them less effective predators? Infected animals find and kill prey less frequently (that is, the parasite caused the value of the search efficiency parameter to decline). the populations would still cycle; the amplitude of prey and predator would increase Othe populations would no longer cycle; the prey would increase and the predator would go extinct the populations would no longer cycle; the prey would go extinct and the predator would increase the populations would still cycle; the amplitude of prey and predator would decline the predator and prey populations would no longer cycle; the parasite and the predator populations would cycle insteadOrganismsthat produce many offspring would best be characterized by which of thefollowing?a.A convex survivorship curveb.A concave survivorship curvec.A linear survivorship curved.A sigmoidal survivorship curvee.None of the choices applySpecies A is present in a community. Species B is introduced to the community. Over the next year, the population sizes of both continual decrease from initial numbers. Which one of the following community interactions might be the cause of this decline? Interspecific competition O Intraspecific competition O Mutualism O Parasitism O Predation
- Which graph best displays the patterns of population abundances as a result of the Lotka-Volterra predator-prey model. The black line represents the PREY population, and the grey line represents the PREDATOR population. x-axis for all graphs = Time а. Graph D O b. Graph C С. Graph A O d. Graph B y-axes = Prey or Predator abundanceA negative feeback loop would be: Preditors and prey keeping each other’s populations in check so there is no overpopulation. Preditors out competeing prey. Prey outcompeting preditors. Both preditors and prey being outcompeted by another organism.In the paired ODE model, the factor that contributes to the growth of the population of the predators is affected by the death rate of the predator affected by the population of the prey directly affected by the rate of predation O always constant
