Energy Flow Through the Biosphere
100
Define energy.
The capacity to do work.
100
What is autotrophy?
The process of self-feeding by creating energy-rich compounds called carbohydrates.
100
What are the main 'product' of primary production?
Carbohydrates.
100
What is a trophic pyramid?
A representation of how energy transfers from one level of organisms to the next as they consume each other.
200
What is the 2nd Thermodynamic Law?
Disorder increases with the passage of time.
200
What is cellular respiration?
The process of releasing energy from carbohydrates to perform the functions of life.
200
Define gross primary productivity.
Measures all organic material produced in an area by autotrophs.
200
What are secondary consumers?
They eat primary consumers. (Mostly zooplankton in the ocean)
300
What is the difference between living systems and machines?
Living systems weren't created by humans/only machines able to reproduce.
300
What is a primary producer?
Autotrophs.
300
What happens when there is too much or too little of limiting factors?
It reduces the population of an organism.
300
What is a food web?
Shows that organisms often have different choices of prey and eat across the trophic pyramid’s theoretical levels.
400
Define cells.
Cells are the smallest whole structure that can be defined as a living system.
400
What is photosynthesis?
The process of using light energy to create carbohydrates from inorganic compounds.
400
What does the term 'Plankton' include?
Auto and heterotrophs, predators, and grazors.
400
What's the difference between a food web and a trophic pyramid?
Trophic pyramid is simpler and shows a direct representation of consumption, and a food web crosses over through different consumers.
500
What are the four elements that make up 99% of living things?
Carbon, Hydrogen, Oxygen, and Nitrogen.
500
Formula for photosynthesis.
6CO2 + 6H2O + light energy ————— > C6H12O6 + 6O2
500
List the four kinds of phytoplankton.
Diatoms, Dinoflagelates, Coccolithophores, and Picoplankton.

Whichever team that got the food web right first wins this!
