- Consider ecological efficiency and energetic hypothesis, why are there few lions than wildebeest in africa ?Suppose that hares are the only prey and food supply of bobcats, and that the predator‒prey interaction follows Lotka‒Volterra dynamics. The mortality rate of bobcats in the absence of rabbits is 0.1 per month. The intrinsic growth rate of rabbits in the absence of predators is 0.2 per month. The attack efficiency of bobcats is 0.004. The efficiency at which hare biomass is converted into bobcat biomass is 0.25. If there are 60 bobcats and 400 hares, the instantaneous rate of change in the hare population will be a ____________ per month, and the instantaneous rate of change in the bobcat population will be a ____________ per month. A. loss of 16 hares; loss of 6 bobcats B. loss of 16 hares; gain of 18 bobcats C. gain of 16 hares; gain of 6 bobcats D. gain of 80 hares; gain of 24 bobcats E. loss of 96 hares; gain of 6 bobcatsSuppose that blue sheep are the most important prey of snow leopard, and that the predator‒prey interaction follows Lotka‒Volterra dynamics. The mortality rate of snow leopard in the absence of blue sheep is 0.1 per week, and the intrinsic growth rate of blue sheep in the absence of snow leopard predation is 0.2 per week. Snow leopard capture efficiency is 0.002, and the efficiency at which blue sheep biomass is converted into snow leopard biomass is 0.2. If there are initially 30 snow leopards and 400 blue sheep, the overall rate of change in the blue sheep population will be a gain of ____ per week.
- Using the concepts of trophic levels and energy flow, explain why the ecological footprint of a vegetarian person is smaller than that of a meat-eaterEcology. As a wildlife biologist, you are responsible for managing white-tailed deer in Ohio. Why would you be interested in knowing the relative importance of density independent and density dependence factors for the deer?“Within a food chain, a prey- predator relationship cause both population to oscillate”. Give an example to prove this statement.
- An ecologist studied how many kangaroo rats could be supported in two different habitats, a high‐quality habitat and a low‐quality habitat. The ecologist estimated the per capita benefit in each habitat as the number of individuals increased.Which of the following might you expect if you increase the amount of energy (and nutrients) into an ecosystem? Group of answer choices increase rates of competition among species increase the consumption of fossil fuels increase the number of trophic levels decrease the standing cropWhich of the following is an example of ecological competition? A. A cheetah chases and kills a gazelleB. Parasites sap resources from an elephantC. Two nearby shrubs take in CO2 for photosynthesisD. One sapling casts a shadow over its neighbors in a dense forest
- Carrying capacity is the maximum number of animals an environment can support. Looking atyour graph, what do you think the carrying capacity for deer might have been? Why?Optimal foraging theory suggest that a predator selects among possible prey based on their relative profitability (energy gained per unit of energy expended). Do you think that predator directly evaluate the profitability of potential prey items before selecting or rejecting them ? If not, how mighta foraging strategy evolve ?Herbivory is beneficial for the animal (+) but harmful to the plant it eats (−). What are some + − interactions among animal populations? What is the difference between commensalism and mutualism?
