Carbon Cycle
What is the primary biological process that removes CO2 from the atmosphere?
Photosynthesis
This group of living things makes its own food using sunlight.
Autotroph
What step of Cellular Respiration breaks down glucose?
Glycolysis
As one of the 6 main environments where carbon is fixed, it is best known for its limited oxygen.
High Anoxic Sediment
How do living organisms (both plants and animals) release carbon back into the atmosphere as a gas?
Cellular Respiration
This group of living things must eat other organisms for energy.
Heterotroph
In which organelle does cellular respiration take place?
Mitochondria
Photosynthesis converts __ energy into ___ energy
Light and Chemical
This step of the Calvin cycle makes a 6-carbon intermediate
Carbon Fixation
What role do decomposers (like fungi and bacteria) play in the carbon cycle?
They break down dead organic matter and waste. This process releases stored carbon back into the soil as nutrients and into the atmosphere as CO2 or methane (CH4)
This molecule acts as the main energy currency for all cells.
ATP
Name the reactants and products of cellular respiration
Reactants: Oxygen and Glucose
Products: Carbon Dioxide, Water and 36 ATP
The products of photosynthesis are the...
a. Products of cellular respiration.
b. Products of glycolysis.
c. Reactants of cellular respiration.
d. Reactants of fermentation.
c. Reactants of cellular respiration.
This gas is taken in by plants from the air to build sugars during the Calvin cycle.
CO2
How does the burning of fossil fuels (combustion) disrupt the natural carbon cycle?
It rapidly releases carbon that was safely trapped deep underground for millions of years (a long-term geological sink) into the atmosphere, causing an imbalance.
This kind of autotroph uses light but also needs organic compounds to make energy
Photoheterotrophs
Cellular Respiration has three steps: glycolysis, electron transport chain and the Kreb's cycle. Place these three steps in the correct order they occur.
Glycolysis -> Krebs Cycle -> Electron Transport
Name the reactants and products of PS
Reactants: Carbon dioxide, Water and Sunlight
Products: Oxygen and Glucose
This cellular respiration stage produces the most ATP molecules.
Electron transport chain
These are the three ways carbon can broken down
Photosynthesis, Sedimentation, and Decomposition
This process allows deep-sea bacteria to make food using chemical energy instead of sunlight.
Chemosynthesis
Write the full equation for CR (formulas)
C6H12O6 + 6O2 --> 6CO2 + 6H20 + 36 ATP
What are the two steps/reactions of photosynthesis
Light Reaction and Dark Reaction
