Review
The organism that introduces energy into an ecosystem.
Producer
A cycle that shows how carbon enters the atmosphere, living organisms, and the ground.
The carbon cycle
Components that go into a chemical process
Where do you find tertiary consumers?
At the top
How animals put carbon back into the air.
Respiration
The cycle that shows how nitrogen enters the ground to provide nutrients for producers.
The nitrogen cycle

How plants put carbon back into the air.
Respiration
What organism provides more than 70% of our Earth's oxygen?
Phytoplankton
How organisms can breathe underwater.
Gills
What products of photosynthesis are starting materials for cellular respiration?

Which row has the most energy?
Producers or bottom row
The burning of fossil fuels.
Combustion
What type of producer takes energy from the sun?
Autotroph
How animals can breathe above water.
Lungs
What happens to glucose inside a cell during cellular respiration?
The cell uses oxygen to break down glucose
Where do decomposers belong?
Below producers or above tertiary consumers (very bottom or very top)
How consumers take carbon from producers.
Eating, consuming
What type of producer takes energy from chemicals coming from thermal vents at the bottom of the ocean?
Chemotroph
Process that uses living organisms to clean up environmental contaminants in soil, water, and other environments.
Bioremediation
Cellular respiration is the process by which cells break down sugars and oxygen to create carbon dioxide, water, and energy. A scientist observes an animal cell and concludes that cellular respiration has taken place. Which of these observations or evidence support the scientist's conclusion. Select all that apply.
A. Sugar is consumed
B. Glucose is increased
C. Oxygen is consumed
D. Water levels are constant
E. Carbon dioxide is produced
F. Mitochondria are found in the cell
A, C, E, F
If the population of the top row of the pyramid were to decrease, how would populations in other levels of the energy pyramid likely change?
They would grow
Organic matter which did not decompose over a long period of time.
Fossil fuels
