Pollution, Population Growth
A method of calculating individual demand on global ecosystems based on resource use and lifestyle is an
ecological footprint
Causes for loss of tropical rainforest are:
cattle ranching, subsistence agriculture and palm oil plantations
The practice of marine invasives species hitchhiking on seaweed or plastics is -
rafting
In the carbon cycle, plants:
Take in CO2 and give off O2,
The practice of dragging a net behind a boat that results in loss of nontargeted species as bycatch is
trawling
When there is a high proportion of a population in the younger age classes, the growth rate will be
high
. The main causes for the loss of grasslands are:
agriculture and grazing
Two reasons invasive species can become established are:
lack native predators, outcompete or prey on natives.
Two effects on coral reefs associated with climate change are –
bleaching and acidification
Reasons scalloped hammerheads are targeted and overharvested is
shark fins
Two effects of discarded plastics on marine life are
entanglement in nets, biomagnified in food webs
The fishing method of dragging a large net behind a boat causing indiscriminate catch is:
trawling
Introduced fish that has venomous spines and has devastated coral reefs by preying on native fish –
lionfish
Three self-maintaining feedback loops associated with climate change are:
photosynthesis, phytoplankton, and polar ice
The illegal and unsustainable over-hunting of animals in forests, mainly primates in Africa is
bushmeat trade
The concentrations of contaminants increasing with increasing trophic level of food webs is called
biomagnification
Pronghorn migration is impacted by:
fences
Invasive vine that grows over other plants, smothering light is:
kudzu
The two major causes of increased CO2 are
burning of fossil fuels and deforestation
Adverse ecological effects of aquaculture include
spreading of disease, fish waste, antibiotics, and escaped fish
Runoff of fertilizers and sewage which kills off aquatic life due to the overgrowth of algae, decomposition, and depletion of oxygen is
eutrophication
Hatchling sea turtles and bird migrations can be adversely affected by –
lights
Invasive reptile that has devastated small mammal populations in the Florida Everglades
Burmese python
Effects of climate change include
Spread of disease, phenology changes, land use changes, species shifts, loss of biodiversity
Popular social media trend that is fueling the illegal wildlife trade –
