Suppose you radioactively label some carbon atoms in the atmosphere so that their movements
can be tracked. Based on your knowledge of the carbon cycle, what process or set of processes
would lead to the transfer of a labeled carbon into biological tissues?
a. photosynthesis
b. photosynthesis and respiration
c. respiration, photosynthesis, and burning of fossil fuels
d. decomposition and respiration - CORRECT ANSWER-a.
The intermediate disturbance hypothesis states that
a. species diversity is highest at moderate levels of disturbance
b. species diversity is lowest at intermediate successional stages
c. environments with the lowest levels of disturbance have the highest species diversity
d. species diversity gradually increases as succession progresses - CORRECT ANSWER-a.
Net primary production is:
a. the total amount of primary production in a given area
, b. highest at 30 degrees latitude in terrestrial environments
c. very low in zones of oceanic upwelling
d. thought to be limited by nutrients in marine environments - CORRECT ANSWER-d.
In terrestrial environments, soils that are warmer and/or more moist are generally poorer in
nutrients. This is because
a. decomposition of organic material in warm/moist soils is nutrient limited
b. decomposition of organic material in warm/moist soils releases lower quantities of nutrients
c. warm/moist soils experience a faster rate of decomposition
d. warm/moist soils experience a slower rate of decomposition - CORRECT ANSWER-c.
A fish biologist uses the mark-recapture experiment to estimate the population size of a species
of fish in a lake. She tags 100 fish on her first sampling. Several weeks later she captures 80 fish,
of which 20 were previously tagged. What is the estimate of N?
a. 400
b. 600
c. 2000
d. 1600 - CORRECT ANSWER-a.
________ are major life zones characterized by vegetation type or physical environment, such
as tundra, desert, grassland, and temperate broadleaf forest. - CORRECT ANSWER-Biomes
During ecological succession, when the presence of one species promotes the establishment of
another species this is called ___________ - CORRECT ANSWER-Facilitation
____________ are organisms, such as beavers, that have a large impact on ecosystems because
they actively modify significant parts of the environment - CORRECT ANSWER-Ecosystem
Engineers
