ECOSYSTEMS
What is nitrogen fixation? (CED p.48)
The process that converts atmospheric nitrogen into ammonia through bacteria found in root nodules.
What is an indicator species? (CED p.66)
A species whose population size is an indicator of environmental conditions is known as this.
This term describes the maximum population an environment can support. (CED p.76)
What is carrying capacity
This layer of Earth is made of solid rock and tectonic plates. (CED p.91)
What is the lithosphere
This pollutant forms when sulfur dioxide and nitrogen oxides react with water vapor. (CED p.110-116)
What is acid rain?
What are producers/autotrophs? (CED p.52)
Organisms that make their own food.
This biome contains permanently frozen soil called permafrost.(CED p.62)
What is a TUNDRA
What is exponential growth? (CED p.80)
A population growing rapidly in a J-shaped curve.
What is a divergent boundary? (CED p.88)
This type of boundary forms when tectonic plates move apart.
What is eutrophication? (CED p.117)
Excess nutrients in water causing algal blooms
What are environmental disturbances? (CED p.64)
An ecosystem with high species diversity.
A national park originally covered 2,400 km² but lost 600 km² due to development. What percentage remains? (CED p.64)
What is 75%
The number of individuals per unit area is called this. (CED p.80)
What is population density?
A region receives 80 cm of rain yearly and loses 50 cm through evaporation. What is the net water gain? (CED p.93-95)
What is 30 cm
Carbon dioxide is classified as this type of pollutant. (CED p.105)
What is a greenhouse gas?
If grass contains 10,000 kcal of energy, how much energy is available to the primary consumer? (CED p.41)
What is 1,000 kcal
Small isolated populations are more vulnerable to extinction because of reduced this. (CED p. 63)
What is genetic diversity?
What are density-dependent factors? (CED p.77)
Factors like disease and competition are examples of population controls.
What is El Nino and La Nina? (CED p.96)
They are phenomena's associated with changing ocean surface temperatures in the Pacific Ocean, while also affecting rainfall, wind, and ocean circulation patterns.
factory emits 400 tons of pollution and cuts emissions by 25%. How many tons are reduced? (CED p.117)
What is 100 tons?
Phytoplankton contain 50,000 kcal of energy. Using the 10% rule, calculate the energy available to secondary consumers. (CED p.41)
What is 500 kcal
Tropical rainforests have high biodiversity because of this climate condition. (CED p.62)
What is warm temperatures and high rainfall?
A town has 2,000 people and grows by 10%. What is the new population? (CED p.74-77)
What is 2,200 people
A region receives 80 cm of rain yearly and loses 50 cm through evaporation. What is the net water gain?
(CED p.93-96)
What is 30 cm?
This air pollutant is especially harmful to human lungs and respiratory systems. (CED p.114 and 116)
What is particulate matter?
