sustainable development - ANS-development or progress that meets the needs of the present
without compromising the ability of future generations to meet their needs
biome - ANS-a large area with the same climate and vegetation
ecotone - ANS-a transitional region between ecosystems
top-down regulation - ANS-control of a population (species) by predation. Predators control the
deer
keystone species - ANS-play a crucial role in maintaining ecosystem biotic structure
food wed - ANS-a combination of all the food chains in a community
primary succession - ANS-the process of initial invasion and progression from one community to
another
endemic and specialized species - ANS-What species are vulnerable to extinction?
Coral bleaching - ANS-the process when corals become white due to various stressors, such as
changes in temperature, light, or nutrients.
yes - ANS-Do humans regulate their reproduction?
Industrial Revolution - ANS-A period of rapid growth in the use of machines in manufacturing
and production that began in the mid-1700s. Resulted in pollution and resource exploitation.
Medical Revolution - ANS-High reproductive rates were balanced with high mortality rates
Green revolution - ANS-Rapid diffusion of new agricultural technology, especially new high-yield
seeds and fertilizers. Pesticides, irrigation, and fertilizer increased yields. Erosion, soil and water
pollution, loss of native plants
Epidemiologic Transition - ANS-the pattern of change in mortality factors
fertility transition - ANS-The decline of birthrates from high levels to low levels in a population.
This transition did not happen at the same time as the epidemiologic transition
- ANS-Causes of mortality in developed countries
