What are autotrophs
producers
What is the importance of producers
create all usable energy on the planet
What are heterotrophs
consumers
Types of consumers
herbivores carnivores omnivores
Importance of consumers
balance the number of producer and other consumers in an environment
What are decomposers
organisms that break down dead and decaying organisms to obtain energy
Importance of decomposers
break down matter and recycle nutrients back into the environment
Food chain
diagram of the energy transfer among organisms in an ecosystem
Each step in a food chain that demonstrates the transfer of energy is called
trophic level
What happens when one organism is removed from a food chain
it interferes with the process of all the organisms in that chain
Only …… of energy is passed from trophic level to the next
10%
How is the remaining energy that passes through a trophic level used
used in life processes or lost as heat
