100
In a food web, which direction does the arrow point to?
Points to the organism which will consume the other organism (the direction the energy will flow)
100
Where does photosynthesis take place in a plant cell?
Chloroplast
100
Does respiration store or release energy? How?
Release energy from glucose to make ATP
100
What are the two processes which primarily drive the carbon cycle?
Photosynthesis & Respiration
100
What organism(s) provide all the energy for this food web?
Grasses
200
What is the type of organism at the top of a food pyramid called?
Apex predator
200
What kind of organisms go through photosynthesis?
Plants only
200
What are the products of respiration?
CO2, H2O, and ATP
200
What is one way in which humans interfere with the carbon cycle?
Burning of fossil fuels
Deforestation
Factory Emissions
etc.
200
How is a food chain different from a foob web?
Food chains show 1 direction of energy (feeding relationship), while a food web shows all the directions of energy (feeding relationships)
300
This type of organism eat plants and animals? What kind of consumer can these be?
Omnivore, have to be a 1 and either 2/3 or 1, 2, and 3
300
What are the reactants of photosynthesis?
CO2, H2O, and sunlight
300
Where in a cell does respiration take place?
mitochondria
300
What types of organisms break down dead matter, releasing carbon back into the soil and atmosphere.
Decomposers
300
Label each organism in the food chain.
grass - producer
grasshopper - primary consumer
mouse - secondary consumer
owl - tertiary consumer
400
In an ecological pyramid, the top of the pyramid has the _________ amount of energy, while the bottom has the ___________ amount of energy
least (top)
most (bottom)
400
What are products of photosynthesis?
Glucose and oxygen
400
What is the purpose of cell respiration?
Break down chemical energy (food) to create ATP
400
Why are total carbon levels remaining the same, but atmospheric levels of carbon are increasing?
We have a total carbon reservoir that doesn't change, but fossil fuels are being removed from deep in the Earth and released into the atmosphere. Plants are being cut down so less CO2 is removed.
400
How much energy is available to the all levels of the pyramid if 650,000 J is available? 
Must give numbers.
500
What percent of energy is available to each level ?
100% at bottom and then 10% goes up the pyramid
500
Does photosynthesis store or release energy? How?
Stores energy when it builds glucose
500
What are the reactants of respiration?
Oxygen and glucose
500
Where is most of the carbon on Earth located?
The ocean

Come up to the board and show the class 2 food chains that make one of the consumers more than one kind of consumer.
Will vary
