animals 9. ConsumersEAT!
Herbivores, carnivores, and omnivores EAT!
They are calledconsumersbecause theyEAT .
10. We can make afood chainto show theflow of energythrough the
organisms! Grass-> Zebra->Lion 11. Here s how we label the
organisms in our food chain. Grass-> Zebra->LionProducer 1st
Consumer 2 ndConsumer P C 1 C 2 A simple way to label! 12.
If the number ofzebra increased , would the amount
ofgrassincrease, decrease or stay the same?
The amount ofgrass would decreasebecause there would be more
zebras eating it.
Grass->Zebra->Lion 13.
If the amount ofgrass decreased , would the number
ofzebraincrease, decrease or stay the same?
The number ofzebra would decreasebecause there would not be
enough food for the zebras.
Grass->Zebra->Lion 14.
If thelionsstarted dying anddecreasedin number, would the
number ofzebrasincrease, decrease or stay the same ?
The number ofzebras would increasebecause there would be fewer
lions to eat them!
Grass->Zebra->Lion 15. Food chains always start with a
producer.
Why?
Because the producer can make food using energy from the
sun!
16. After a while organisms die.Then the decomposers get busy!
Fungilike mold and mushrooms andbacteria break downdead organisms
and rot them away!!They aredecomposers .
