What are autotrophs/producers
This is the chemical symbol for atmospheric Nitrogen.
What is N2?
What do arrows represent in a food web?
The flow/transfer of energy
A series of events in which one organism eats another and obtains energy. Usually written on one line.
What is a food chain?

What is tertiary?
The exhaust from a car, the burning of coal in a furnace are both examples of adding CO2 to the atmosphere from this method.
The burning of fossil fuels.
which trophic level of the energy pyramid has the largest biomass and why?
Producers/autotrophs because they have the largest amount of energy
An organism that breaks down wastes and dead organisms.
What is a decomposer?
This is a way to show how energy in a food web is allocated. Usually there is a large base and a pointed top.
What is an energy pyramid?
The step of the water cycle where plants release water vapor into the atmosphere via open stomata in the leaves.
What is Transpiration?

120 kCal of energy
The process of burning off carbon-based products such as gasoline and propane, creating carbon dioxide
Combustion

What is bacteria?
A forest fire burns down several trees in a forest. Compared to normal levels, what would happen to the amount of CO2, O2 , and the biomass of the area if it was measured a few days later?
The amount of CO2 would be higher
The amount of O2 would be lower
