Trophic Levels
How much energy is available to the next trophic level?
10%, Rule of Ten
What is the source of energy for all producers?
The sun/light energy
What is needed for cellular respiration?
Glucose and Oxygen
Where do Zombie Fires occur?
Boreal Forests (subarctic)
Name 3 Keystone Species
Otters, Wildebeest, Wolves, Starfish, Wild-Dogs, Bass, etc.
Grass is at what energy level?
Producer (Plant does NOT count)
What is a waste product of photosynthesis?
Oxygen
What type of respiration occurs without oxygen?
Anaerobic Respiration / Fermentation
What is the fuel for a Zombie Fire?
Peat
What was driving the wildebeest migration?
Food availability. Followed the rainy seasons.
What is a heterotroph?
What is the organelle of photosynthesis?
Chloroplasts
What is the organelle of cellular respiration?
Mitochondria
How do plants turn into peat?
By dying and being broken down by the decomposers in the soil.
List three limiting factors in an ecosystem.
food availability, space, predation, competition for resources, natural disasters, climate, humans, disease, etc.
What energy level should have the least amount of organisms?
Tertiary Consumer/Apex Predator
Where does the light dependent reaction occur?
Thylakoid
Which step in Aerobic Respiration produces 34 ATP?
The ETC (Electron Transport Chain)
What is the climate concern regarding the Zombie Fires?
They release large amounts of CO2 into the air which is a greenhouse gas and contributes to climate change.
What refers to the specific set of conditions an animal prefers/the role an animal plays in its ecosystem?
Niche
What happens to the energy lost between trophic levels?
It is "lost" as heat to the environment
During the light independent reaction, what is the series of chemical reactions responsible for converting ATP and CO2 into glucose and oxygen?
Calvin Cycle
What is the preferred type of respiration? Include at least 2 reasons WHY?
Aerobic Respiration. Produces 36-38 ATP instead of 2 ATP. Also has no harmful bi-product like lactic acid or ethanol.
Why can the Zombie Fires burn through the winter and others don't?
The peat has enough energy to supply the fire throughout the colder months. Most other fire fuel will not have enough energy to outlast the cold.
If an animal is living outside of its preferred niche, but not in its intolerance zone, what zone is the animal in?
Zone of physiological stress
