One characteristic that distinguishes a populationin an extinction vortex from most otherpopulations is that(A) it is a rare, top-level predator.(B) its effective population size is lower than itstotal population size.(C) its genetic diversity is very low.(D) it is not well adapted to edge conditions.
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.
The process of species replacement over time in a community is called (a) global climate change. (b) succession. (c) competition. (d) community change.

They found that, as of 2005, approximately 50,000 species had been introduced in the United States and that these accountedfor over $120 billion in economic costs each year. These costs include direct losses and damage, as well as costs required to control the species. (The researchers did not quantify monetary estimates for losses of biodiversity, ecosystem services, and aesthetics, which they said would drive total costs several times higher.) Calculate values missing from the table to determine the number of introduced species of each type of organism and the annual cost that each imposes on our economy.
