Nutrient Cycles
In the water cycle, what process is responsible for water vapor turning back into liquid?
Condensation
What is the main organelle that carries out photosynthesis?
Chloroplast
Where does the electron transport chain take place?
Mitochondria
Name a way in which heat is lost in the energy pyramid from one trophic level to the next
Metabolic processes, heat...
In our yeast lab, what cellular respiration process occurred and what were the products?
Anaerobic respiration (fermentation) which created ethanol and Carbon Dioxide.
What is the largest Carbon Sink?
Limestone
What are the products of photosynthesis?
Oxygen, glucose
What is respiration that happens without Oxygen?
Anaerobic Respiration
What is another name for consumers
heterotrophs
What is produced at the end of glycolysis?
Pyruvates
Phosphorus is essential for all living organisms because it is a key component of:
DNA and RNA
What are the reactants of photosynthesis?
Carbon, water and sunlight
What molecules do animal and plant cells use to power activities in the cell?
Glucose
What is the difference between Food Webs and Food Chains
Food chains show a simple pathway and food webs show every possible pathway for energy in an ecosystem
Predict what might happen to an ecosystem if the carbon cycle is disrupted by increased deforestation.
Carbon levels in the atmosphere will increase causing global warming
Name two ways carbon dioxide is released into the atmosphere.
Combustion,
Deforestation,
Mining...
What is another name used to refer to primary producers?
Autotrophs
Which of the following is the first step in aerobic respiration?
Explain Net Primary Productivity (NPP)
The total energy passed on by plants to other organisms. (Total energy - energy needed for metabolic processes).
What is the main difference between detritivores and decomposers
Detritivores: consume and digest
Consumers: break down using chemicals
What is the main thing that sets the phosphorus cycle apart from the other nutrient cycles?
Phosphorus does not have an atmospheric component
What is the relationship between cellular respiration and photosynthesis
The products of photosynthesis are the reactants of cellular respiration and the products of cellular respiration are the reactants of photosynthesis.
What are the reactants for cellular respiration?
Glucose and Oxygen
Explain the 10% rule in the transfer of energy.
Only 10% of energy is transferred from one trophic level to the next
What are the three steps of aerobic cellular respiration?
Glycolysis, Krebs Cycle, Electron Transport Chain
