Grasshopper
100
Which cycle includes the following processes: precipitation, condensation, evaporation, transpiration, runoff
Water
100
What word means: living or once living
biotic
100
What is carrying capacity?
The maximum number of individuals an area can support
100
What are the 2 main nutrients that might cause eutrophication in a body of water?
Nitrogen and Phosphorus
200
What is the energy source for photosynthesis?
Sun
200
In the carbon cycle, what is the main source of too much carbon doxide in the atmosphere?
Combustion of fossil fuels
200
What is the difference between a community and a population?
Community is made of many different living organisms and a population is one species of living organisms
200
Name two causes that would decrease the carrying capacity of an area
Less food, water, resources, shelter
More disease
200
Why do farmers use fertilizers?
To add nutrients to their plants to help them grow (nitrogen and phosphorus)
300
What would happen to the squirrel population if all their food source (acorn nuts) decreased?
Squirrel’s would decrease with a lack of food
300
What are 2 solutions that would cause less build up of greenhouse gasses in the atmosphere?
Renewable resources (solar, wind,etc), and planting of trees
300
What does ‘bio’ mean?
Living
300
During what historical time period did we see a rise in the global population and increase use of fossil fuels and more greenhouse gasses in the atmosphere?
Industrial Revolution
300
What is a GMO?
Genetically Modified Organism
400
According to the 10% rule, how much biomass would the owl receive if the grass has a biomass of 616 g?
Grass-->Grasshopper-->Mouse -->Owl
0.616 g
400
What would happen in the nitrogen cycle if there were no bacteria?
No bacteria = cycle cannot continue to because nitrates would not get attached to plants roots
400
What is the difference between a community and ecosystem?
Ecosystem includes the living and non living things in an area, where a community is ONLY the living things in an area
400
As the human population increases and their activities increase, what effect does this have on our water and atmosphere?
More water pollution and usage
More air pollution (more greenhouse gasses)
400
How does eutrophication create a dead zone?
There is no oxygen in the water (hypoxia) because the bacteria absorb it all through decomposition when the algae and plants die

500
Are GMOS good or bad? Support with 2 pieces of evidence
(UP TO TEACHER DISCRETION)
Good Evidence:
Helps grow more food in a shorter amount of time.
Helps food last longer.
Helps get nutrients not normally available.
Bad Evidence:
Can lead to antibiotic resistance or pesticide resistance.
Haven’t been around long enough to determine negative effects on humans.
Has a negative effect long term on the environment
