PRODUCERS/AUTOTROPH are organisms that can transform energy from sunlight and/or chemicals, and use it to produce plant matter or food.

Self Feed

Page 4: FL#3. Standard 6e = Students know a vital part of an ecosystem is the stability of its producers and decomposers

Without PRODUCERS the subsequent HERBIVORES in a FOOD CHAIN or WEB would have no source of sustenance (nutrients).

Page 5: FL#3. Standard 6e = Students know a vital part of an ecosystem is the stability of its producers and decomposers

DECOMPOSERS are organisms that can break down (and obtain nutrients and energy from) dead organic matter. DECOMPOSERS are the “recyclers” of the ecosystem.

Page 6: FL#3. Standard 6e = Students know a vital part of an ecosystem is the stability of its producers and decomposers

Without DECOMPOSERS organic material would not be broken down and nutrients would not be recycled back into the soil. PRODUCERS (plants) would then not be able to obtain the necessary nutrients from the soil.
