Based on the graph above, which of the following years postdisturbance had the greatest species richness?
100
Calculate the percent decrease in the otter population from 1995 to 2000.
13%
Based on the graph above, which of the following years postdisturbance did sweetgum experience the greatest biomass?
50
Which of the following is an example of an ecosystem service that would provide protection from a hurricane storm surge?
An intact coastal wetland
Based on the theory of island biogeography, which of the following islands would most likely have the highest number of species living on it?
An island 30 hectares in size that is 10 kilometers off the coast of the mainland
An island off the coast of Africa contains a larger percentage of specialist species than generalist species. Which of the following describes the most immediate effect if an invasive generalist species is introduced to the island?
As competition for resources increases, the population size of the island's specialist species will decrease.
Which of the following best describes the trends in atmospheric CO2 concentration and Antarctic temperature over the past 800,000 years?
Atmospheric CO2 concentration and Antarctic temperature are directly correlated over the past 800,000 years.
Which of the following ecosystem services is categorized as regulating?
Pollination, decomposition, and water purification
Which of the following economic consequences to a provisioning ecosystem service will most likely result from increased global warming?
The collapse of local fisheries, because of the damage to coral reefs from ocean acidification
The image shows two different islands and the relative distance to the nearest mainland. Based on the theory of island biogeography, which of the following best predicts the effect of the introduction of an invasive species on Easter Island compared to Madagascar?
The native species on Madagascar are more likely to survive because the island is larger and provides a greater diversity of habitats and resources.
Based on the graph above, which of the following tree species would be the predominant species found during the intermediate stage of succession?
Tulip poplar
which of the following scenarios represents a habitat that will begin to undergo the process of secondary succession?
an agricultural field recently harvested and left unplanted
the area under the curve depicted by the letter B would be best described as
the niche of a specialist, such as panda bear, which only eats bamboo
species richness is defined as
the number of different species within a community
what generalized trend is observed from 1983 to 2007 on this graph?
the otter population is showing a slow rate of increase
All of the following are true of climax communities EXCEPT
they are considered to be mid successional communities
which habitat has the greatest species richness?
tropical rainforest
