100
A species that no longer exists in one part of Canada, but can be found in others.
What is extirpated.
100
What is the difference between food chains and food webs?
What is food chain shows the flow of energy through these organisms, food web is many interwoven food chains
100
The second law of thermodynamics
What is energy is lost to heat when changing forms.
100
What are the 4 main parts to the water cycle?
What is evaporation, condensation, precipitation, accumulation.
100
Biotic potential depends on these four factors.
What is birth potential (# babies born at one time), capacity for survival (how many survive to have their own babies), Procreation (the number of times that a species reproduces in a year), length of reproductive life (how fast after being born they can have babies, and for how long)
200
Five abiotic factors
What is light, temperature, wind, moisture, soil.
200
What is the difference between habitat and niche?
What is habitat is a specific space where an organism lives, niche is the role that an organism plays in its environment.
200
What level of a food chain has the largest energy stored inside?
What is the bottom level (producers)
200
What are the main components of the carbon cycle?
What is respiration, photosynthesis, oceans, and fossil fuels.
200
This formula represents what number? [(births + immigration) - (deaths + emigration) ]/initial population number *100
What is population growth rate.
300
Increase in the concentration of toxins in the tissue of an organism that is higher on the food chain
What is bioamplification/biomagnification.
300
What is the difference between biotic and abiotic?
What is biotic is living components of an ecosystem, and abiotic is non-living components.
300
How much energy is lost with each transfer in the food web?
What is 90%
300
What are the main components of the nitrogen cycle?
What is bacteria (nitrogen fixing, nitrite converting, and denitrifying), plants, and the atmosphere.
300
What is population density?
What is number of individuals per unit area.
400
What is a trophic level?
What is the feeding level of an organism in a food chain.
400
How does removing trees affect biodiversity vs. the carbon cycle?
What is biodiversity = less organisms, less variety of life, less roots to hold soil in, shelter, water, etc Carbon cycle = less photosynthesis, burning trees releases carbon into atmosphere
400
Give an example of a food chain (with niche) with the following organisms: Owl, grass hopper, bird, grass.
What is Grass (producer), grasshopper (primary consumer), bird (secondary consumer), owl (tertiary consumer).
400
Name one way that humans affect the carbon cycle
What is burning fossil fuels, forest fires, increase in population,
400
Four ways populations change size?
What is natality (births), mortality (deaths), immigration, emigration.
500
What is the difference between the hydrosphere and the lithosphere?
What is hydrosphere is the water on the planet, while the lithosphere is the land areas.
500
Difference between a producer and a primary consumer?
What is producer makes its own food, and a primary consumer eats producers (it is the first on the food chain to eat another organism)
500
What are the reactants and products of photosynthesis?
What is reactants area carbon dioxide, water, and energy --> sugar and oxygen.
500
Describe a way that humans influence the nitrogen cycle.
What is pesticides, increased number of organisms.
500
What is carrying capacity and steady state?
What is carrying capacity is the maximum number of organism that an area can support without harming the environment, and steady state is when the population reaches an equilibrium (gaining and losing population at the same rate)
