Question

29.The data suggests that global climate change stems from what human activity?

A)burning of fossil fuels   B)depleting the ozone layer   C)the burying of toxic wastes

D)the incineration of municipal wastes   E)a and b but not c and d

30.The number of individuals of a species that can be maintained in an area (by the resources in that area) over time is termed the area's:

A)maximum level  B)carrying capacity  C)stable peak  D)niche optimum  E)biotic potential

31. The idea that the City of New York would spend money to buy land around their reservoirs in the Catskills (because the land acts a natural filtration system) instead of spending money to build a water filtration plant to clean the water as it arrives in NYC from the reservoirs is an example of the recognition of….. (note: this is a highly simplified description)

A. law of conservation of matter        B. law of conservation of energy  C.  the 2^nd law of thermodynamics (the entropy law)    D. external costs   E. ecosystem services

32. Ecological diversity is a measure of the number of

A. different kinds of organisms within a community or ecosystem.

B. different versions of the same gene in an ecological community.

C. sizes, colors, and shapes of organisms within an ecological community.

D. trophic levels in a biological community.

E. different microhabitats in an ecosystem.

Answer 1

29)

Correct choice is A

Loss of ozone layer and incineration of municipal waste also affects climate change. But to a lesser extent. Burning fossil fuels is the prime human activity causing climate change.

30)

Correct choice is B

Carrying capacity is the maximum population size of the species that the environment can sustain indefinitely by the resources of food, habitat, water and other necessities.

31)

Correct choice is E

Ecosystem services.

Ecosystem services are the many and varied benefits to humans gifted by the natural environment and healthy ecosystem.

32)

Correct choice is A

Measured by number of species. Or different kinds of organisms in an ecosystem or community.

Phylogenetics is important in diversity of ecology. But its not about a single gene.

Trophic levels are important but species diversity is more important.

Microhabitat is a small localized ecosystem within a large ecosystem. Example a decomposing log.
