- Question 4 When disturbance is frequent, competition is often less intense. Question 4 options: A) True B) False Question 5 Directional selection on the niche to reduce overlap leads to ___________. (two words) Question 6 In a coevolutionary arms race ____________. A) selection favors equilibrium. B) each adaptation by one species negates selection on the other. C) each adaptation by one species leads to a new adaptation in the other. D) selection is stronger on the predator.K-strategists __________. Question 10 options: typically produce larger offspring are typically fast-growing organisms typically produce many offspring typically have boom and bust cycles of population growth typically have low parental investmentWhich statments are correct? Question 25 options: Species diversity tends to increase with evapostranspiration Species diversity tends to increase with when parasitism is low Species diversity tends to increase with island area Species diversity tends to be higher when disturbance frequency is low Species diversity tends to increase with decreasing latitude
- Figure 45.10b If the major food source of the seals declines due to pollution or overfishing, which of the following would likely occur? The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same. The number of seal deaths would increase but the number of births would also increase, so the population size would remain the same. The carrying capacity of seals would remain the same, but the population of seals would decrease.It's ecology, i need to draw a chart to solve this tho. Thank you! I'll leave a thumb up You are quantifying competition between two species of flour beetles. For species 1, K1 = 160 and α = 1. For species 2, K2 = 360 and b = 4. Suppose the initial population sizes are 180 of species 1 and 80 of species 2. Predict the short-term dynamics of each population and the final outcome of interspecific competition.29. The competitive exclusion principle states that species that compete for the same resource in the same way: will end up with one eating the other to extinction. will have population numbers that cycle in response to one another. cannot coexist and one will outcompete the other. usually find a way to coexist.
- A coyote population in Colorado has 40 individuals, the potential reproductive rate per individual per year is 1.5, and the carrying capacity of the area is 50 coyotes. In the same habitat, the bobcat population has 30 individuals, the potential reproductive rate per individual per year is 2, and the carrying capacity of the area is 100 bobcats. The bobcats depress population growth of coyotes through competition by 0.20, while the coyotes depress population growth of bobcats through competition by 1.1. What will the population size be for coyotes next year? *Note that this is the other half of the bobcat question, and you need to round your answer to a whole animal. 40 5 45 16 55The 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?1. Based on the graph, determine the population of carabao in: i. 4 years: 2. Based on the graph, determine the population of carabao in: ii. 5 years:3. Based on the graph, determine the population of carabao in: iii. 6 years:4.

- Question 1 ___________ competition occurs when one species reduces the resource available to the other. __________ competition occurs when one species reduces access to the resource. Question 2 Which of the following is not characteristic of interspecific competition? Question 2 options: A) Two or more species interact. B) The population size of at least one species decreases. C) The limiting resource does not change over time. D) One or more resources is limiting. Question 9 In a type II functional response ____________. Question 9 options: A) as handling time decreases, consumption also decreases. B) consumption is limited by handling time at very high prey density. C) as search time increases, consumption also increases.…For the cricket, the intrinsic growth rate is 100 and the carrying capacity of the environment is 200,000 individuals. For the frog, the capture efficiency is 0.0002, the conversion efficiency is 0.1, the handling time per cricket is 0.2 hours, and the density-independent per capita death rate of the predator is 0.4. 18. At what value of the number of crickets is the predator population of frogs at equilibrium? 19. What is the dN/dt of the prey population when the number of frogs is 60 and the number of crickets is 11,000? Round to the nearest hundredth. 20. What is the dP/dt of the predator population when the number of frogs is 60 and the number of crickets is 11,000? Round to the nearest hundredth.Density-dependent factors __________. have a greater impact at higher population densities are less important for regulating population size than density-independent factors act at the community level cause decreases in numbers of species in an ecosystem as a result of temperature extremes
