Question
Read the following scenario and answer the questions below.Human activities release greenhouses gases, which cause measurable warming of Earth. This warming can alter ecosystem dynamics, through direct and indirect effects. Direct effects may include changes in growth and other metabolic rates of organisms with a rising temperature. Indirect effects may be caused by changes in the ecosystem: shrinking of sea ice, increases in precipitation in Arctic areas, retreat of glaciers, melting permafrost in the tundra, and increase in the intensity of hurricanes in vulnerable areas. Within communities, climatic change can shift interdependent species "out-of-sync," potentially causing indirect loss of species.
If the climate warms significantly, glaciers may retreat . This may start the process of ________.
A) primary succession
B) secondary succession
C) coevolution
D) climax
E) facilitation
