The Living World: Ecosystems
A grassland ecosystem contains grass which then is eaten by the grasshopper, then eaten by the frog, then eaten by the snake, then eaten by the hawk. (Identify the trophic level of the frog)
What is a secondary consumer?
(Pg. 52)
This type of adaptation involves how an organism acts.
What is a behavioral adaptation?
(Pg. 65)
These species have a broad niche and can live in many different environments.
What are generalist species?
(Pg. 72)
This process breaks down the rock into smaller particles that eventually form soil.
What is weathering?
(Pg. 89)
What is tragedy of the commons?
(Pg. 103)
This productivity measurement accounts for energy lost to respiration by plants.
What is net primary productivity (NPP)?
(Pg. 51)
Larger islands tend to have this compared to smaller islands.
What is greater species diversity?
(Pg. 62)
This survivorship curve shows a constant death rate throughout life.
What is Type ll?
(Pg. 75)
This soil component comes from decomposed plants and animals.
What is organic matter (humus)?
(Pg. 90)
One major environmental impact of clearcutting is this.
What is habitat destruction?
(Pg. 104)
Burning fossil fuels contributes to this major environmental issue due to increased CO2 levels.
What is climate change (global warming)?
(Pg. 47)
Outside the tolerance range, organisms experience this.
What is stress or death?
(Pg. 63)
The maximum population size an environment can support is called this.
What is carrying capacity?
(Pg. 77)
Most weather occurs in this atmospheric layer.
What is the troposphere?
(Pg. 91)
One environmental downside of the Green Revolution is this.
What is soil degradation or pesticide pollution?
(Pg. 105)
A wetland ecosystem shows a decrease in available nitrogen due to bacteria converting nitrates into nitrogen gas. (Identify the process)
What is denitrification? It reduces available nitrogen in the soil, limiting plant growth.
(Pg. 48)
After a forest fire, grasses and small plants begin to regrow quickly. (Identify the type of succession)
What is secondary succession?
(Pg. 66)
A country's age structure diagram has a narrow base and wider top (Predict the population trend)
What is a declining population?
(Pg. 78)
Air rises at the equator due to this process.
What is warm air expansion?
(Pg. 92)
This pesticide type was heavily used but is now banned in many places due to bioaccumalation.
What are persistent pesticides?
(Pg. 106)
A farmer is studying energy flow in a grassland ecosystem. Each year, 20,000 kcal of solar energy reaches the field. Only 5% of that energy is converted into chemical energy by plants.
A rabbit eats the plants, a snake eats the rabbit, and a hawk eats the snake.
20,000 * 0.05 = 1,000 kcal
1,000 * 0.10 = 100
100 * 0.10 = 10
10 * 0.10 = 1 kcal
How much energy is available to the hawk? (The 10% Rule)
(Pg. 53)

What is 160 species?
After serval years, Island A has 200 species, while Island B has 40 species, what is the difference in species richness.
What is 160 species?
After serval years, Island A has 120 species, while Island B has 30 species, what is the difference in species richness.
