A builder is proposing a new housing development in an area of central Florida. Construction of the housing development will destroy the wetland habitat in the area. Which of the following would be the most likely consequence of the wetland destruction?
a.The populations of wetland animals would be unable to survive in that area.b.The populations of wetland plants would evolve to disperse seeds by wind rather than water.
c.The wetland animal species would survive by interbreeding with non-wetland species.a.The populations of wetland animals would be unable to survive in that area.
A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida. Which of the following is a likely impact of this catastrophic event on biodiversity?
a.Species brought in by the storm surge will displace species native to the coastal wetlands.
b.Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
c.Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity will increase in these areas.
d.Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the local species, causing a decrease in biodiversity.
b.Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.
Which could be a possible consequence of increased ocean acidification due to acid rain?
l. relocation of organisms
ll. disruption to food web

c.The temperature of the ocean is rising in the ocean and the pH is decreasing making the ocean slightly less acidicd.The temperature of the ocean is rising in the ocean and the pH is decreasing making the ocean slightly less basic
d.The temperature of the ocean is rising in the ocean and the pH is decreasing making the ocean slightly less basic
Whaling was a very profitable profession until whale populations crashed. The global community came together to enact a ban on whaling. However, Japan and Norway have not agreed to stop whaling. Which of the following is the most likely consequence of their decision?
a.The whales are getting better at avoiding capture.c.The whale populations are not rebounding as quickly as they might if all of the countries agreed not to hunt whales.
Which of following examples can be classified as a loss of biodiversity due to climate change?
a.a new building on previously protected land
b.carbon emissions causing higher atmospheric temperatures
c.lion fish being set free into coastal waters
d.tsunami causing massive erosion
b.carbon emissions causing higher atmospheric temperatures
Which of the following scenarios would not decrease the diversity within that environment?
a.An exotic species of fish is released into an estuary to control a pest species.
b.Trout are released into a lake that already contains trout to increase the population size.
c.A hurricane hits an island hard and wipes out a large number of animals only found on that island.
d.Climate change causes the temperature of an ecosystem to drop lower than what many species in that environment can tolerate.
b.Trout are released into a lake that already contains trout to increase the population size.
Ecosystems consist of living and non-living components that contribute to the size, health, and diversity of the habitat.
