This biome has the coldest temperatures, and very little rainfall. (1.1b)
What is the tundra.
100
This biome is a northern coniferous forest that is found just below the Arctic Circle. (1.1b)
What is the taiga.
100
A group of organisms of the same species living in a specific area and interbreed. (1.1a)
What is population.
100
These things limit the growth of a population. (6.1f)
What is limiting resources (factors).
100
Exponential growth graphs show population growing at this rate. (6.1f)
What is constant.
200
This biome is found at the equator, has high temperatures, and an abundance of rainfall. (1.1b)
What is the tropical rain forest.
200
This biomes is known for its tall grasses and flat landscape. (1.1b)
What is the grasslands.
200
The number of births minus the number of deaths determine this of a population. (1.1a)
What is growth rate.
200
More deaths than births in a population would cause this to occur. (1.1a)
What is a decrease in population.
200
Trees which lose their leaves are most common in this biome. (1.1a)
What is the temperate rain forest.
300
These two abiotic factors determine which biome develops in an area. (1.1b)
What is temperature and precipitation.
300
Climates of biomes vary because of these two factors. (1.1b)
What is latitude and altitude.
300
This is the number of individuals per unit area or volume. (1.1a)
What is density.
300
Exponential growth can only occur under these conditions. (6.1f)
What is ideal (plenty of food, space, water, mates, and no competition, or predation).
300
Predator-prey relationship graphs show these two things. (6.1f)
What is limiting factors and carrying capacity.
400
Succulents are most common in this biome. (6.2a)
What is the desert.
400
This human activity is causing threats to forest biomes. (1.1f, 6.3c)
What is deforestation.
400
This occurs when a population grows at a faster and faster rate with each generation. (6.1f)
What is exponential growth.
400
The reproductive potential of an individual increases most when this occurs. (4.1a)
What is reproduction occurs earlier in life.
400
Penguins are often seen standing huddled, or clumped, together which is an example of this. (1.1a)
What is dispersion.
500
Sunlight can not reach the floor of a tropical rain forest because the canopy is too dense for light to penetrate. There is a lack of this on the forest floor despite what we see in movies. (1.1b)
What is vegetation.
500
Prairie fires, both natural and man made, affect the evolution of fire resistant prairie grasses because it causes this. (3.1h)
What is a decrease in genetic variability.
500
Animals defend this for its food, water, space, and breeding sites. (6.1f)
What is a territory.
500
One bacterium producing 19 million descendants in its lifetime is an example of this. (4.1a)
What is reproductive potential.
500
The root systems in grassland ecosystems help to stabilize the soil which prevent this from happening. (1.1b)
