Autotrophs belong to what trophic level?
Producers or primary producers
100
What is area of a quadrat that is 2m by 2m
4m^2
200
Rain carries nutrients across land and into the bay in this process
run off
200
Which type of organisms get energy directly from the sun
Producers or autotrophs
200
What is the name of the river in the inner harbor?
The Patapsco river
200
What is the name of the tropic level that eats producers?
Primary consumers
200
What is the area of this quadrat?
1m x 1m= 2m^2
300
What is transpiration
Water evaporating off of leaves due to sunlight
300
What process converts solar energy into food molecules such as glucose
Photosynthesis
300
Which area of the bay would you expect to have the highest salinity?
The lower bay
300
What would happen to mouse populations if wild cats go extinct?
Mice would increase with their predator gone
300
If there are 8 flowers inside the quadrat what is the density? (Density= number of organisms/ area)
8 flowers/ 2m^2 = 4 flowers/ meter
400
What is the producer in most aquatic ecosystems
Algae and submerged aquatic vegetation such as kelp and sea grass
400
Solar power for electricity is gaining popularity due to it's role in reducing carbon emissions. What energy source is known for increasing carbon emissions?
Fossil fuels
400
Name a autotroph in the Chesapeake Bay food web
400
What would happen to the green plant population if wild cats went extinct?
The population would decrease because mouse populations would increase and mice feed on green plants

If the density of sea stars is 2 stars per meter (2 stars / 1 m2) predict the density in the entire 10 meter sampling area.
( ( 2 stars / 1 m2)=(x stars/10 meter) )
cross multiply
(2 stars) *(10 m2) = (x stars) * (1 m2)
20 = X * 1
20/ 1 = X * 1 / 1
20=x
500
What is salinity
the amount of salt found in water
500
What happens to the total amount of energy in ecosystems as you move up the food web?
It decreases, It is lost, lost as heat
500
Which organism have more energy available Pond snail or the great blue heron
500
Which organism is a tertiary consumer in this food web?
Hawks or snakes

If the density of sea stars is 4 stars per meter (4 stars / 12 m2) predict the density in the entire 120 meter sampling area.
( ( 4 stars / 12 m2)=(x stars/120 meter) )
1. Cross multiply
(4 stars * 120 meters) = (x stars) * (12 meterts)
480= 12x
2. Solve for X
480/ 12 = 12x/12
40= X
