.Autotroph- make their own food
Ex. Grass, algae, bacteria – to make food from sunlight
Eat other organisms
Heterotrophs- eat producers and consumers
Kinds of consumers1. Carnivore- eat animals
2. Herbivore- eat plants
3. Omnivore- eat plants and animals

Scavengers- omnivores that eat dead plants and animals.

(Fungi and Bacteria) – “Nature’s Recyclers”
Food Chain- series of events in which one organism eats another
and obtains energy.
Food Web- a diagram that shows the feeding relationships
between organisms in an ecosystem. (land and aquatic), several
food chains together
A triangular diagram that shows an ecosystem’s loss of energy,
which results as energy passes through the ecosystem’s food

One species can be very important to the flow of energy in an
environment.
As wolves become reestablished in Yellowstone National Park,
they kill the old, injured and diseased elk which helps control
