Heterotrophs are organisms that cannot make their own food; they are also called this because they must consume other organisms for energy
What are consumers?
100
Each level on a energy pyramid or food web is called a ________ __________
What is a trophic level?
100
Number 4 on this diagram of the water cycle, water leaves the atmosphere in the form of rain or snow
What is precipitation?

The aphids are this trophic level
What are primary consumers?
200
Number one on this diagram of the water cycle, water seeps into the ground to become groundwater
What is percolation?
200
Letter C on this diagram of the carbon cycle, where plants take carbon dioxide out of the atmosphere
What is photosynthesis?
200
Bacteria A is called this, and it converts nitrogen from the atmosphere into ammonia
What is nitrogen-fixing bacteria?
200
Number 1 of the Nitrogen Cycle, found in the atmosphere
What is N2, or atmospheric nitrogen gas?
300
The raccoon eats blueberries, eggs, and fish. Because it eats both plants and animals, it is classified as a __________
What is an omnivore?
300
The snakes are at this trophic level
What is tertiary consumer?
300
Number 6 on the water cycle diagram, water in the atmosphere changes from a gas to a liquid and forms clouds
What is condensation?
300
Photosynthesis allows autotrophs to make their own food, and it also removes this from the atmosphere and releases oxygen
What is carbon dioxide?
or
CO2
