Another Link in the Food Chain

Everyone plays a specific role

in the food chain of life. You might be a human thinking they are king of the hill or you might be a bacterium under the feet.
You are very important to the survival of the system no matter what role you play.

Food Chains and Webs

You will see the terms food chains and

food webs. They describe the same series of events that happen when one organism consumes another to survive.

Food Chains and Webs You will see the terms food

Слайд 6

Food web is a more accurate term since every organism is

involved with several other organisms.

Food web is a more accurate term since every organism is involved with several other organisms.

The Producers

Producers are the beginning of a simple food chain.

Producers are plants and vegetables.

The Producers Producers are the beginning of a simple food chain. Producers are plants and vegetables.

Слайд 8

The Producers

All energy comes from the Sun and plants are

the ones who make food with that energy. They use the process of photosynthesis. Plants also make loads of other nutrients for other organisms to eat.

The Producers All energy comes from the Sun and plants

The Consumers

Consumers are the next link in a food

chain. There are three levels of consumers.

The Consumers Consumers are the next link in a food

Слайд 10

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

Tertiary consumers (3rd order) Eat the primary and secondary consumers

Слайд 11

Omnivores eat both plants and meat
They can be EITHER primary or

secondary consumers.

Omnivores eat both plants and meat They can be EITHER primary or secondary consumers.

Scavengers
=They eat the remains of dead organisms left by the consumers
-

vultures, coyotes, hyenas

Scavengers =They eat the remains of dead organisms left by the consumers - vultures, coyotes, hyenas

Слайд 13

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 Decomposers

The last links in the chain are the decomposers. (They

Слайд 14

Decomposers break down nutrients in the dead "stuff" and return it

to the soil.

The producers can then use the nutrients and elements once it's in the soil.

The decomposers complete the system, returning essential molecules to the producers.

Decomposers break down nutrients in the dead "stuff" and return
