This organelle is known as the "Powerhouse of the Cell"
What are mitochondria?
Approximately what % of energy is "lost" as heat in ecosystems?
What is the difference between AEROBIC and ANAEROBIC Respiration?
AEROBIC = with Oxygen
ANAEROBIC = without Oxygen
What is the effect of planting more trees in an area?
Increased trees means that there is more photosynthesis occurring. More photosynthesis means there is more food for animals, which means that more animals can live.
What is the difference between an Exergonic and Endergonic reaction?
**bonus points for providing an example of each (+100)**
Exergonic = release energy because they are breaking bonds of molecules
Endergonic = input of energy because they are creating bonds
Possible Examples: Exergonic: Cellular Respiration Endergonic: Photosynthesis
What is the equation for Photosynthesis (balanced) and what are the names of the inputs and outputs?
Sunlight + 6CO2 + 6H2O = C6H12O6 + 6O2
Sunlight (light energy), Carbon Dioxide and Water (inputs)
Glucose and Oxygen (outputs)
What is the equation for Cellular Respiration (balanced) and what are the names of the inputs and outputs?
C6H12O6 + 6O2 = ATP + 6CO2 + 6H2O
Glucose and Oxygen (inputs)
ATP (energy), Carbon Dioxide and Water
This process will cease to occur if Raleigh were to go through a drought next summer.
What is photosynthesis
What macromolecule LOWERS the activation energy required to begin a reaction?
Enzymes (proteins)
Why is photosynthesis so important?
Photosynthesis converts sun energy into food, making energy available for plants and animals. It also makes Oxygen, which we need to breathe.
This is the difference between AUTOTROPHS and HETEROTROPHS
**bonus points - what are the levels of heterotrophs/consumers in an ecosystem? +200pts**
What is AUTOTROPHS are self-feeding or provide their own food and HETEROTROPHS feed on others or rely on another organism for food.
**bonus - Primary, Secondary, Tertiary, Quaternary/Apex Predator**
Does energy flow through a system or cycle?
**What Law of Thermodynamics tells us this is true? +200pts**
What is flows?
*1st Law of Thermodynamics, energy cannot be created or destroyed, only transferred or transformed*
The holes in the bottom of leaves through which carbon dioxide enters the leaf.
What are stomata?
What is the cycle made by photosynthesis and cellular respiration?
The cycle that keeps the amounts of carbon dioxide and oxygen fairly constant in the atmosphere, also known as the Carbon Cycle
If 3,500 Kcal is available to the producers in this ecosystem, how much energy will be obtained by the tertiary consumer?
*show your work*
3.5 Kcal
3,500 -(x.10)> 350 -(x.10)> 35 -(x.10)> 3.5
Producer -> 1 Consumer -> 2 Consumer -> 3 Consumer
Do the atoms that make up carbon dioxide, water, and sugar flow or cycle through a system?
**bonus - Provide evidence +500**
What is cycle?
**the same inputs of photosynthesis are the outputs of cellular respiration and vice versa**
