This type of consumer eats both plants and animals.
(Omnivore)
If 10% of energy moves to the next level, where does the other 90% go?
(Lost as heat or metabolic processes)
Which process is more efficient (makes more ATP): Cellular Respiration or Fermentation?
(Cellular Respiration)
What is the name of the pigment that plants use to absorb energy from the sun?
(Chlorophyll)
Where does the Electron Transport Chain take place?
(The inner membrane of the mitochondria)
What is the difference between a food chain and a food web?
(Chain = one path; Web = multiple paths/overlapping chains)
If a primary consumer contains 500 Joules of energy, how much will the secondary consumer obtain?
(50 Joules)

How do gases enter and exit plants through openings in the leaves?
(Stomata)
Which part of cellular respiration produces 2 pyruvate molecules?
(Glycolysis)
This organism feeds off of decomposing organic matter.
(Detritivore or Decomposer)
Why is a pyramid shape used to represent energy?
(Because energy/biomass decreases as you move up)
What type of respiration produces ethanol and CO2?
(Alcoholic fermentation)
What two molecules are created during the light-dependent reactions to power the Calvin Cycle?
(ATP and NADPH)
During which specific stage of respiration is CO2 produced?
(The Krebs Cycle)
