Which of the following statements about the carrying capacity is NOT true? Select one: a. We can think of K as some "average" value that a given environment can support. b.

Vultures are 4x as large as crows and eat 4x as much. They also can chase Crows away from carcasses. Therefore, one additional vulture in an area displaces four crows, but it takes 10 additional crows to displace one vulture. The competition coefficients are O alpha12 (imaging the greek alpha with subsript 12) = 10, alpha21 = 4 O alpha12 = 4, alpha21 = 10 O alpha12 = 4, alpha21 = 0.1 O alpha12 0.1, alpha21 = 4arrow_forwardNt= N0 t represents:a.geometric population growth.b.annual growth rate.c.exponential growth rate.d.logistic growth.e.none of the choices apply.arrow_forward
- In the land between the lakes, Elk and Bison Prairie, we currently have 125 bison and 15 elk. These species are known to compete for some but not all of their resources. We are able to determine that the carrying capacity of the bison K1 is 200 and that the alpha (competition coefficient) is 4. The carrying capacity for Elk (K2) is 100 and the beta (competition coefficient) is 1.arrow_forwardA population of 200 bass released in a lake began growing at a rate of 100 fish/yr. A second assessment performed at a later date found that there were 400 fish and the population was growing at a rate of 160 fish/yr. (Assume logistic growth dynamics.)
