Food Chains

SOL 3.53rd Grade Science

Presentation by Elaine Bennett

Producers

Make their own food

Plants are Producers They make their

food from the SUN, WATER, and NUTRIENTS in the soil

Consumers

Can’t make their own food Need to get food from other animals

or plants 3 types of Consumers

Herbivores Carnivores Omnivores

Consumers- Herbivores

Eat only plants

Deer Cows Mice

Consumers- Carnivores

Eat other animals (meat) Known as Predators- catch

and kill their Prey (the animal that is eaten)

Tigers Frogs (eat flies) Sharks

Consumers- Omnivores

Eat both plants and animals

Humans Raccoons Bears Pigs

Decomposers

Eat dead plants and animals

Help clean up dead bodies

Fungi (mushrooms) Bacteria Worms

Food Chain

All of these organisms interact to form a food chain

Almost always stars with a plant (a producer)

An herbivore eats the plant, then a carnivore eats the herbivore

Grass mouse fox producer…consumer….consumer

Food Webs

Many animals are involved in Food Webs.

More than one consumer eats the same type of food.

Consumers also eat many types of foods.

Food Web Example

-Producer leaf, grass

-Consumer(herbivore)

caterpiller,cricket,mouse

-Consumer (carnivore)

robin, spider, fox, bear

-Decomposer fungi, bacteria

*remember, decomposers eat dead animals

Summary

The students learned that all of the organisms on Earth are connected through the food chain.

Humans are even part of it. We eat plants and animals. If we lived in the wild, we may become prey to larger animals (sharks)
