Food Chain and Food Webs
How do organisms interact with one another in a food chain/food web?

In the beginning, there was a…
Producer: an organism that makes it’s own food.
Most producers make food through the process of photosynthesis.
Another word for producer is autotroph.

Examples of producers:
Plants Phytoplankton

Where do you think most producers get the energy to make their own food?
Answer:The Sun!

Who eats the producers?
Consumers: an organism that has to eat to get its energy.
Another word for consumers is heterotroph.

3 types of Heterotrophs:Herbivore: An organism who
only eats plants.Carnivore: An organism who
only eats meat.Omnivore: An organism who
eats both plants and animals.

What is each of these animals?Talk with your neighbor and see what they think.

But wait, there’s more!Scavengers: Animals that
eat dead animals or carrion (rotting flesh).
They help break down organic material into smaller pieces.

Last but not least:
Decomposers: Organisms that eat fragments of dead matter in an ecosystem.
They are also called: DetritivoresImportant to an ecosystem
because they return nutrients back to the air, water, and soil where they can be reused!

Some examples:
Bacteria
Worms and InsectsFungi, like
mushrooms

So what are food chains? Shows how each organism gets its
energy (food). Always starts with a producer and uses
arrows to point the direction where energy is moving..

A Food Web: Shows complex
feeding relationships between organisms in an ecosystem.
Uses multiple arrows because most organisms feed on more than one species.
