50,000 kcal of energy is available to the producers. How much is available to the primary consumer?
5,000 kcal
200
Organisms that only eat plants
herbivores, primary consumers
200
How water enters the atmosphere
Evaporation and/or transpiration
300
Why there are fewer tertiary consumers than primary consumers
Less energy is available to them

Fungus and bacteria fill this ecological role
Decomposer

What happens if more CO2 is added to the atmosphere than is removed?
Heat gets trapped in atmosphere, global temperatures increase.
400
Where the lost energy goes
Into the atmosphere as heat or undigested as feces.

What is the most efficient food source for the eagle to consume? Why?
Rat: the are 2' consumers only. All others are 3' or higher. Less energy lost through trophic levels.
