30. Food Chain- A series of events in
which one organism eats another to obtain energy
In this food chain a flower is eaten by a caterpillar which is eaten by a frog which is eaten by a snake which is eaten by an owl
Flower caterpillar frog snake owl
Tell me some things that you notice about this food chain
ALL food chains start with a producer
What do you think would happen to us if there were no plants in the world?
We would starve to death. All food chains begin with a producer so even the carnivores ultimately rely on plants
Hold it just one second! Actually, all food
chains start with the sun because that is where plants get their energy from
Your turn! Make a food chain that
has at least 4 members Don’t forget that all
food chains start with a producer
Label the members of your food chain as:
-producer -1st order consumer - 2nd order
consumer - 3rd order consumer
What organism is at the top of your food chain?
The organisms at the top are usually your big predators.
Such as, a bear, a shark , an eagle
Guess who else is at the top
That’s right, humans are!
There aren’t too many things that eat a human
Strange but true…. Sometimes a food
chain only consists of 2 organisms
Like a human eating an apple
31. Food Web- A series of
overlapping food chains
Looks confusing! Start with a plant and follow the
arrows
32. Food Pyramid- A diagram that shows
the amount of energy that moves from one feeding level to another in a food web
Energy is lost at each level of the food pyramid
The food pyramid is often called the energy pyramid
