- Define secondary succession, eutrophication, and climax communityProvide the marine environment based on the characteristics given and 2 potential primary producer that are attached to the respective environment.Briefly explain how some of the threats associated with the Tundra Biome can also be threats to other biomes and other parts of the world.
- Environmental scientists David Pimentel, Rodolfo Zuniga, and Doug Morrison of Cornell University reviewed scientific estimates for the economic and ecological costs imposed by introduced and invasive species in the United States. 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. Of the 50,000 species introduced into the UnitedStates, half are plants.
