What is the difference between a specialist species and a generalist species.
Generalist species can feed on a wide variety of things and thrive in various environments. Specialist species eat a limited diet and occupy a much narrower niche
Identify 5 types of marine biomes
Marshes, Swamps, Tidal zones, Open Ocean, Coral Reefs
What is the difference between divergent boundary and convergent boundary?
Convergent boundaries have plates that move towards each other, whereas divergent boundaries have plates that move away.
Which of the following best illustrates a sustainable approach to mitigate climate change?
a)removing limits on greenhouse gas emission
b)shifting away from fossil fuel based energy sources to solar power
c)cutting down forests for agricultural and urban development
d)increasing reliance on fossil fuels for transportation
B
Define Tragedy of the Commons
The seas, air, water, animals, and minerals are all “the commons” and are for humans to use, but those who exploit them become rich.
Which cycle has denitrification and what does that mean.
Denitrification is when nitrate is converted to nitrogen gas and returned to the atmosphere.
What age structure shape depicts a stable, or zero growth in a population
Which soil type will likely provide the best drainage desert plants, and why?
Sand, Loam, or Clay
Sandy, because its permeability is high.
Identify one disadvantage of aquaculture compared to wild fisheries.
Aquaculture practices rely more on antibiotics to reduce the spread of diseases. A disadvantage of aquaculture is that it relies more on antibiotics to control disease.
Fossil fuels are usually found below ground, and humans use a variety of methods to extract them.
Which extraction methods are commonly used to remove natural gas from the earth?
Horizontal drilling and fracking or drilling vertical wells
Which of the following best characterize the littoral zone of a lake/
It receives enough sunlight and nutrients for rooted plants t survive.
What is the theory of island biogeography?
It proposes that the number of species found on an “island” is determined by immigration and extinction of isolated populations.
Identify the second most abundant gas in this region, which comprises of the air.
Oxygen
The Ogallala Aquifer is at risk of depletion because its rate of withdrawal exceeds its rate of recharge.
Why do aquifers, like the Ogallala, tend to have an increasing withdrawal rate?
Growing residential and industrial needs are depleting aquifers faster over time. The withdrawal of water due to growing residential and industrial needs has caused an increase in the withdrawal rate.
Why do geothermal energy generators operate at a higher capacity than solar energy generators?
Geothermal energy is accessible in all light conditions.
Geothermal energy comes from deep within the Earth and is not impacted by the amount of light, which increases the capacity to generate energy this way.
Which of the following features of the carbon cycle is most closely associated with cellular respiration?
a) ocean water
b) geologic reserves of fossil fuels
c) the atmosphere
d) plants and animals
d) plants and animals: Cellular respiration occurs in living organisms who convert carbon-based food molecules and oxygen into carbon-based energy storage compounds.
What is the difference between the 3 different types of survivorship curves
Organisms that exhibit Type I survivorship invest heavily in the care of the small number of offspring they produce, resulting in a high percentage of organisms surviving over time.
Organisms that exhibit Type II survivorship have a constant proportion of individuals dying throughout the life cycle.
Type III survivorship curves represent populations that have a high death rate among the young, but a relatively low death rate for those who survive into middle and old age
What occurs in El Nino and La Nina?
An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña.
Would the development of drought-tolerant crop plants be considered a benefit or a risk of genetic engineering in agriculture, and why?
Benefit, because land once unsuitable for growing could be turned into productive farmland. Developing GMO plants that can produce food on dry land is a benefit because it increases food production capacity.
Name all of the stages in population growth
Stage 1: pre - Industrial (High Stationary)
Stage 2: Transitional (Early Expanding)
Stage 3: Industrial (Late Expanding)
Stage 4:Post- Industrial (Low Stationary
Stage 5: Sub- Replacement Fertility (Declining)
How do you calculate birth rate
( Total births/total population ) x 100
According to the rule of 70, what is the doubling time for a nation with a population growth rate of 10 per year?
7 years
What formula determines population growth?
[(CBR + immigration) – (CDR + emigration)]/10
The half-life of strontium-90 is 25 years. How much strontium-90 will remain after 100 years if the initial amount is 4.0 g?
0.25 grams
How do you calculate doubling time.
70/ Growth Rate %
