True/False:
Humans are autotrophs because we produce our own energy.
FALSE
True/False
Consumers/heterotrophs are found at the bottom of the pyramid.
FALSE
Which sphere best describes the oceans, lakes, and rivers on Earth?
Hydrosphere
Which of Earth's spheres can we find carbon in?
Analyze the graph by describing what happens on the x-axis and y-axis.
Use words like increase, decrease, or stays the same.
Pitcher plant population (PPP) decreases
Insect population increases
True/False
A food web has many producers and many consumers.
Identify which organism receives the most energy.
(1) Jaguars because they are the strongest predator.
(2) Bananas because they are consumers.
(3) Fruit flies because they eat bananas.
(4) Bananas because they get energy from the light.

Bananas because they get energy from the light.
Which sphere do humans live in? Why?
Biosphere because we are living things.
Why do plants need carbon?
Plants need carbon for photosynthesis.
Based on the model, where is there more carbon and why?
The internal environment of the plant because it shows 5000 ppm, while the external environment only has 400 ppm.
Give one example of an autotroph and one example of a heterotroph.
Many different answers accepted.
If the number of producers decreases, what will happen to herbivores (primary consumers)? Why?
They will decrease because they have less food available.
If carbon moves from the air into the ocean, which two spheres are involved?
Atmosphere and hydrosphere
How do humans impact the carbon levels in the atmosphere?
Humans increase the carbon levels in the atmosphere.
When a regents-question asks you to "use evidence from the graph", what do you need to say in your response?
"The graph shows..."
"One piece of evidence from the graph is..."
Identify two different organisms in the food web and describe how they interact.
Multiple answers accepted.
Describe 1 pattern (organization) you see in the energy pyramid.

Multiple answers accepted.
How is the geosphere different from the atmosphere?
The geosphere includes rocks, soil, and the ground. However, the atmosphere includes gases in the air.
If the number of plants/trees decreases, what would happen to the amount of carbon in the atmosphere? Why?
The amount of carbon in the atmosphere would increase because there are less producers to absorb it and use it.
If you see a model with numbers, what should you do before answering the question?
Annotate the model and identify which numbers are high/big and which are low/small.
State 1 predator in the food web and 1 prey in the food web. Explain why for each.
Multiple answers accepted.
As you move up an energy pyramid, what happens to the amount of available energy?

It decreases because it's lost as heat to the environment.
Describe one interaction between the atmosphere and biosphere.
Multiple answers accepted.
If the amount of trees/plants increases, what would happen to the amount of carbon in the atmosphere?
The amount of carbon in the atmosphere would decrease because there are more producers that absorb and use it.
Based on the graph, describe the pattern (organization) you see happening to atmospheric carbon dioxide levels.
The carbon dioxide levels in the atmosphere are increasing overtime.
