The type of energy that starts photosynthesis
Radiant Energy
Also known as Primary Consumers
Herbivores
Organisms found at the first trophic level
Autotrophs, Plants, or Producers
The arrow in a food web shows
Direction of energy flow
The gas we breath out that plants use for photosynthesis
Carbon Dioxide
The part of the plant that absorbs Carbon Dioxide
Stomata
Organisms that must eat to obtain energy, aka consumers
Heterotrophs

Organisms at the third trophic level
Snakes
The amount of energy available to be passed to each trophic level
10%
Shows all the possible feeding relationships in an ecosystem
Food Web
The reactants of Photosynthesis
Carbon Dioxide and Water
Organisms that can use radiant energy to create chemical energy
Autotrophs
The trophic level where Secondary Consumers are found
Third Trophic Level
The way most of an organism's energy is lost/spent
As heat to the environment
The plant structure that absorbs radiant energy
Chlorophyll
Where photosynthesis occurs
Chloroplast

The Tertiary Consumer
Dolphin
The trophic level where Primary Consumers are found
Second Trophic Level
The trophic level with the most amount of energy
First Trophic Level
. The organism receiving the smallest amount of energy
Hawk
The purpose of photosynthesis
Convert radiant energy into chemical energy
Breakdown dead organisms and waste, returning matter to the environment
Decomposers
The trophic level(s) where decomposers feed
All trophic levels except the first
The type of energy heterotrophs can consume
Chemical Energy
The total number of oxygen atoms on the reactant side
18 atoms of Oxygen
