BIOMES
100
A series of predictable changes that occurs in a community over time due to natural or human disturbances.
What is: A) ecological succession B) primary succession
100
The relationship between a hermit crab and a ragworm would be ________________. The ragworm uses the hermit crab's shell for a shelter and gets crumbs from the crab's mouth.
What is: A) Symbiosis B) Commensalism C) Mutualism
100
Oak tree masting events creates:
What is: A) Larger populations of other species B) Decreased rate of predation among species
100
95% of organism's bodies are made up of phosphorus, carbon, hydrogen, and _________________.
What is: A) Oxygen B) Potassium C) Nitrogen
100
Which biome would have greater productivity: the taiga or the tundra?
What is: A) taiga B) tundra
200
The range of living and non-living conditions in which an organism lives and how it uses those conditions.
What is a(n)? A) habitat B) ecosystem C) niche
200
Which of the following is NOT a limiting nutrient?
What is: A) oxygen B) nitrogen C) phosphorus
200
As a result of the mice population increasing during these masting events, what other population exploded?
What is: A) Oak trees B) Songbirds C) Ticks
200
How does carbon enter producers?
What is: A) through their leaves B) through photosynthesis C) through their roots
200
What happens to average temps and rainfall as you move away from the equator?
What is: A) Increase B) Decrease
300
A type of ecological succession in which a biological community develops from a barren or uninhabited area.
What is: A) primary succession B) secondary succession
300
Which of the following is an example of a pioneer species?
What is: A) fungi B) algae C) tree saplings
300
Which organism is the primary carrier of the bacteria that causes Lyme Disease?
What is: A) Ticks B) Mice C) Acorns
300
How does carbon dioxide enter the atmosphere?
What is: A) cellular respiration B) photosynthesis C) decomposition
300
Why does productivity increase in areas closer to the tropics?
What is: A) There are more plants in those areas, so they attract more animals and other organisms. B) The climate (rainfall, temps, and sunlight) are perfect for high photosynthetic rates.
400
Relationship in which two species live in close association with one another.
What is: A) Mutualism B) Symbiosis C) Ecological succession
400
Which of the following would be a density-independent factor?
What is: A) disease B) drought
400
What happened to the songbird and gypsy moth populations as the mice population increased?
What is: A) Increased B) Decreased
400
Why is nitrogen important to organisms?
What is: A) It is used to make DNA and RNA B) It is used to make proteins C) It is used to make body tissues
400
In which biome would you expect plants to have adapted to grow short instead of tall?
What is: A) Desert B) Tundra
500
A factor that affects population growth because of its population density.
What is: A) density-dependent limiting factor B) density-independent limiting factor
500
Which of the following is an example of secondary succession?
What is: A) A forest is clear cut to make way for a new neighborhood B) A glacier melts in the Arctic.
500
How does the Oak tree masting event make it more likely for humans to get Lyme Disease?
What is: A) The massive amounts of acorns attract larger populations of mice. These mice get infected with the bacteria from ticks. B) The massive amounts of acorns attract larger populations of mice which attract larger populations of ticks. The ticks contract the bacteria that cause Lyme Disease. More ticks means the likelihood for humans to contract the disease increases.
500
Phosphorus is returned to the soil by:
What is: A) Decomposition B) Respiration C) Photosynthesis
500
What would be a limiting factor for the tundra?
What is: A) low temps B) lack of water C) predation
