What is a Food Chain?What is a Food Chain?
A food chain is the path by which energy passes from one living thing to another.
What’s in a Food What’s in a Food Chain?Chain?
Producers
Consumers
Decomposers
ProducersProducers
Producers make their own food
Green plants use energy from the sun to make food
Producers are on the bottom of the food chain
ConsumersConsumers
Consumers hunt, gather, and store food because they cannot make their own.
Three Types of Three Types of ConsumersConsumers
Herbivores
Carnivores
Omnivores
HerbivoresHerbivores
Animals who eat plants such as:–grasshoppers–rabbits–squirrels–deer–pandas
CarnivoresCarnivores
Animals who only eat other animals such as:–tigers– lions–hawks–wolves–cougars
Omnivores eat both plants and meat
–They can be EITHER primary or secondary consumers.
Predator & PreyPredator & Prey
Predator- An animal that captures and eats other animals
Prey- The animal that is captured and eaten
DecomposersDecomposers
Microorganisms that are able to break down large molecules into smaller parts
Decomposers return the nutrients that are in a living thing to the soil
The last links in the chain are the decomposers. (They break things down) Like bacteria, mold, fungi, mushrooms
•If you die, they eat you. •If you poop, they eat that.
•If you lose a leaf, they eat it.
–Whenever something that was alive dies, the decomposers get it.
The The DecomposersDecomposers
–Scavengers–=They eat the remains of dead organisms left by the consumers
–- vultures, coyotes, hyenas
Let’s LookLet’s Lookat aat aFood Food ChainChainA food chain
is a simplified way to look at the energy that passes from producers to consumers.
•Tertiary consumers (3rd order) – Eat the primary and secondary
consumers (CARNIVORES) ex: wolf eats cat and squirrel
•Secondary consumers (2nd Order)–Eat the primary consumers (CARNIVORES) example: cat eats squirrel
•Primary consumers (1st Order)–Worms, insects, squirrels, mice: all eat plants (HERBIVORES) ex: squirrel eats acorns
Types of Food ChainsTypes of Food Chains
Aquatic- Water-related food chains with sea/water plants and animals
Terrestrial- Land-related food chains with land plants and animals
What is a Food Web?What is a Food Web?A more realistic way of looking at the relationship of plants and animals in an environment
Several food chains linked together
A predator from one food chain may be linked to the prey of another food chain
Food WebsFood Webs
How many food chains can you make from this food web?

Let’s Review!Let’s Review!
Summarize how energy derived from the sun is used by plants to produce sugars (photosynthesis) and is transferred within a food chain or food web (terrestrial) from producers to consumers to decomposers. Use at least 5 vocab words.
