Unit 1-2
What organisms in an ecosystem are considered autotrophs... bonus if you can describe what an autotroph is!
- Plants
-Autotrophs: An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
What type of survivorship curve most represents humans?
Type 1
What concept is related to the issue of overfishing?
Tragedy of the commons
What atmospheric condition increases the effects of photochemical smog?
Temperature inversion
place where an organism lives
Habitat
How would a phosphorus-rich runoff impact the surrounding bodies of water?
Simple answer: Eutrophication
Explained: An algal bloom would occur due to excess nutrients in bodies of water. Decomposers would take place and break down algae which then results in a dead zone with no oxygen.
What stage of the demographic transition model is characterized by low birth and death rates?
Stage 4
What consequence would an increase in sedimentation have on a river?
Block's sunlight from ecosystem and lowers water temperature.
Which of the following appliances is known to produce VOCS into the atmoshere?
Paint and varnishes
Rock that forms when magma cools and solidifies
Igneous Rock
What layer of the ocean can sunlight penetrate through?
Photic Zone
Acid rain from air pollution primarily does what to freshwater lakes?
Lowers the ph which harms fish and other wildlife living there.
Which energy source releases the most amount of greenhouse gases per unit produced?
Coal
What air pollutant reduction would most benefit human health?
Particulate Matter
Speciation that occurs when two types of species live in the same area but evolve differently
Sympatric Speciation
What strategy would most effectively lower water usage while protecting agricultural crops?
Going from flood irrigation to a drip irrigation system.
How might an El Nino event affect local fisheries?
Big decline in fish populations due to warmer water temperatures and altered nutrient distribution.
How could climate change undermine the green revolution?
By altering rainfall patterns and increasing droughts that reduce available water for crops.
What agricultural practice would limit the runoff of endocrine disruptors into waterways?
Buffer Strips of vegetation around fields
A large scale convection cell in which air rises at the equator and sinks at medium latitudes typically about 30 degrees north to south.
Hadley Cell
What is adaptive radiation?
A burst of species formation due to natural selection where closely related species have adapted to different food resources, habitats or way of life.
If deforestation occurs at high altitudes what is the most likely effect on precipitation patterns?
Reduced precipitation going down
Percent change equation?
(final value-first value)/initial value
What is a potential long term effect of untreated sewage in waterways?
Eutrophication leading to hypoxic conditions which causes fish die offs.
Microscopic Particles on which water vapor condenses to form cloud droplets.
Condensation Nuclei
