*YOU MUST STUDY YOUR NOTE SHEETS FROM CLASS THAT YOU GLUED INTO YOUR NOTEBOOK*

 Consumers / heterotrophs – identify in an example
Herbivore
Carnivore
Omnivore
Detritivore
Decomposers
 Sun is the main energy source for life on earth
 During photosynthesis producers produce oxygen
B). Energy Flow in Ecosystems
 Describe how energy flows from the sun in an ecosystem
 Food web / food chain – how are they different, can you read energy flow in?
 Trophic level – can you identify which level an organism is in a food chain?
 How much energy is lost at each level of an energy pyramid if the producer level is 10, 000?
C). Cycles in Nature
*REVIEW THIS SECTION FOR YOUR ESSAY QUESTION*

Nitrogen is released to abiotic parts of ecosystem by the process of death and decay by bacteria
Nitrogen fixation – bacteria change nitrogen gas into a usable form
