Unit 1
What is the carbon cycle? page 47
The movement of atoms and molecules containing the element carbon between sources and sinks. page 47
What is Biodiversity?
Page 60
Genetic, species, and ecosystem diversity.
Page 60
What is a survivorship curve?
Page 75.
A line that displays the relative survival rates of a cohort.
Page 75.
Describe agricultural practices that cause environmental damage.
Page 106
Tilling, slash- and burn farming, and the use of fertilizers.
Page 106.
Identify where natural energy resources occur.
Page 131
The global distribution of natural energy resources, such as ores, coal, crude oil, and gas, is not uniform and depends on religion's' geologic history.
Page 131
What do Marine Biomes include? page 46
Oceans, coral reefs, marshlands, and estuaries. page 46
Describe island biogeography
Page 62
The study of the ecological relationships and disruption of organisms on islands and of their community structure.
Page 62
Identify differences between generalist and specialist species.
Page 72.
Specialists: advantage in constant habitats
Generalists: thrive in changing habitats
Page 72.
What are the effects of clearcutting of forests?
Page 104
Soil erosion, increased soil and stream temperatures, and flooding.
Page 104
Describe trends in energy consumption.
Page 129
More industrialization in the world
The most widely used sources of energy globally are fossil fuels.
Page 129.
What do freshwater biomes include? page 46
Streams, rivers, ponds, and lakes. page 46
What are the two types of ecological succession.
Page 66
Primary and secondary succession.
Page 66
Identify differences between K and r- selected species.
Page 74.
r-selected species are minimally affected by invasive species.
K-selected species are typically more adversely affected by invasive species.
Page 74.
Page 103.
Individuals will use shared resources in their own self-interest rather than keeping with the common good, depleting the resources.
Page 103.
Identify differences between nonrenewable resources and renewable resources.
Page 128
Nonrenewable energy sources exist in a fixed amount and involve energy that can't be easily replaced.
Renewable energy sources are those that can be replenished naturally, at or near the rate of consumption and reused.
Page 128
A crop field has a phosphorus concentration of 1.2 P/kg soil. The plants absorb nutrients at a rate of 6 kg/day for 15 days.
Calculate the total amount of phosphorus absorbed by the plants.

Describe the role of island biogeography in evolution.
Page 62
Many island species have evolved to be specialists versus generalists because of the limited resources, such as food and territory on most islands.
Page 62.
A forest can support a max of 600 deer. the current population is 450.
Calculate the percent of carrying capacity the deer population has reached.
Page 75
75%
Page 75
Page 105
A shift to do new agricultural strategies and practices in order to increase food production, with both positive and negative results.
Page 105.
Identify the 3 types of coal used for fuel.
Page 130
Lignite, bituminous, and anthracite.
Page 130.
Name the major terrestrial biomes. page 45
Taiga, temperate rainforests, temperate seasonal forests, tropical, tropical rainforests, shrubland, temperate grasslands, savanna, desert, and tundra. page 45
A forest originally contains 250 species of plants and animals. A wildfire damages 32% of the habitat.
Calculate the number of species expected to be lost.

How does resource availability affect population growth?
Page 77
Population growth is limited by environmental factors, especially by the availability of resources and space.
Page 77
Crop a field with 2,400 insects pests. A biological Control agent is introduced and is 65% effective at reducing the pest population.
Calculate the number of pests remaining after treatment.

A nuclear plant receives 5,000 MWh of energy from nuclear fuel and produces, 1750 MWh of electricity.
Calculate the efficiency of the nuclear power plant.
