- An extinction vortex describes a) changes in a population’s gene pool that lead to a loss in fitness across time. b) a species ability to adapt to changes in their environment. c) the continuous series of extinctions caused by competition between species. d) a population that has a reduction in fitness because it cannot escape a Hardy-Weinberg Equilibrium.arrow_forwardA population of 1,492 finches is introduced to a rainforest. Over the next year, the finches show a death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers) a) Yes, this is a suitable habitat. The birth rate is higher than the death rate. b) No, this is not a suitable habitat. The birth rate is much lower than the death rate. c) 589 d) -358 e) 0.155 f) 0.845arrow_forwardSupport for the individualistic model of community structure includes (a) the decline of honeybees because of two species of parasitic mites (b) the identification of fig trees as a keystone species in tropical forests (c) the competitive exclusion of one Paramecium species by another (d) the distribution of trees along a moisture gradient in Wisconsin forests (e) theeffects of the removal of a dominant rodent species from an Arizona desertarrow_forward
- The principle of competitive exclusion states that(A) two species cannot coexist in the same habitat.(B) competition between two species always causes extinctionor emigration of one species.(C) two species that have exactly the same niche cannot coexistin a community.(D) two species will stop reproducing until one species leavesthe habitatarrow_forwardThe process of species replacement over time in a community is called (a) global climate change. (b) succession. (c) competition. (d) community change.arrow_forwardWhich of the following statement is incorrect about the two broad classes of explanation of interspecific distribution abundance relationships? (a) The first class postulates the existence of a positive feedback between local abundance and the regional distribution of a species. (b) Species that occur in large number across many localities will be more likely to maintain their wide distribution and high abundance. (c) Consequence of positive feedback is that there is no dichotomy. (d) The consequence of positive feedback is that there is dichotomy, species will be either widespread or abundant or they will be restricted and scarce. This division helps in the knowledge and in turn helps to categorize them accordingly as restricted or widespread species.arrow_forward
