Population Growth
The pattern of human population growth is
exponential
Reasons scalloped hammerheads are targeted and overharvested
shark fins
In the water cycle, the process that follows the evaporation of water that is carried by wind which cools,
condenses and falls to land as precipitation
Two ways that pollutants get into water bodies are
point and non-point sources
In the carbon cycle, plants take in
CO2 and give off O2,
The number of males and females in each age class is the
population age structure
Planting only one type of crop plant is called a
monoculture
Loss of wetlands has resulted in
increased flooding, erosion, and loss of habitat
Sources of pathogens in water include
untreated sewage, feedlot waste
The two major causes of increased CO2 are
burning of fossil fuels and deforestation
When there is a high proportion of a population in the younger age classes, the growth rate will be
high
The practice of dragging a net behind a boat that results in loss of nontargeted species as bycatch is
trawling
Disruptions to the water cycle include
depleting aquifers, dams, urbanization, and climate change
Runoff of nutrients that stimulates algal blooms and fish kills is called
eutrophication
Three self-maintaining feedback loops associated with climate change are:
photosynthesis, phytoplankton, and polar ice
A method of calculating individual demand on global ecosystems based on resource use and lifestyle is
an ecological footprint
The illegal and unsustainable over-hunting of animals in forests, mainly primates in Africa is the
bushmeat trade
Effects of climate change on the water cycle include
increased glacier and snow melt, increased flooding and soil erosion, and intensity of storms
Sources of metal pollution include
coal plants, mine drainage, agricultural pesticides
The effect of increased temperature on coral reefs associated with climate change is called
coral bleaching
The relationship between human population growth and species extinction is a
parallel increase
Adverse ecological effects of aquaculture include spreading of disease, fish waste, antibiotics, and escaped fish
spreading of disease, fish waste, antibiotics, and escaped fish
The two methods of desalination are
distillation and reverse osmosis
Warm/hot water released from industrial pipes results in
reduced oxygen level of water, causes thermal shock
Effects of climate change include
spread of disease, phenology changes, land use changes, species shifts, loss of biodiversity
