When Yellowstone National Park was created in the late 1800s, the grey wolf population was not protected, which led to the elimination of the population in 1926. In 1995, 21 wolves were reintroduced in Yellowstone National Park. Reintroducing wolves to Yellowstone National Park resulted in Select one: a. an increase in cougar population due to decreased intraspecific competition b. a decrease in cougar population due to increased intraspecific competition c. an increase in cougar population due to decreased interspecific competition d. a decrease in cougar population due to increased 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.

57. Lobster is a very valuable seafood export in Canada. The lobsters caught off the coast of Atlantic Canada make up 50% of the world lobster supply. In order to protect the lobster population from overfishing, the Government of Canada has conservation measures in place to ensure the population size is maintained. Some of the measurements include placing a limit on the number of fishing licenses issued, limiting the fishing seasons, establishing minimum and maximum lobster size limits, and protecting egg-bearing females. Fisheries and Oceans Canada regularly monitors and collects data to estimate the lobster population size.The carrying capacity of the lobster population can be best described as the Select one: a. initial bottom plateau in a logistic growth curve that demonstrates a stable population b. steep increase in an exponential growth curve that demonstrates the high biotic potential c. slow increase in a linear growth curve that demonstrates controlled and sustainable…

A. reciprocal evolutionary change among interacting species B. an antagonistic relationship, where both participants have lower fitness C. a mutualistic relationship, where both participants benefit D. a change in allele frequency in a population over time E. adaptations to the physical environment
32. What is a species? Group of answer choices a.Two populations that only interbreed very occasionally or rarely if at all. b.An interbreeding population. c.Two populations that never interbreed.
37. When 2 different species are competing for a resource, in the absence of other factors, one will usually win because the competition is asymmetrical. That is because: One species usually cheats. Populations have different numbers of individuals. Different species have different morphologies (how they look) and physiologies (how they function). All of the choices are true.
