Food Chain Shows how energy from organisms passes from one organism to another Shaped like a chain

Food Web A diagram that shows the transfer of energy and food relationships between organisms in an ecosystem Several food chains put together Looks like a spider web

Food Web What does all this mean? The leaves passes energy to the cricket The cricket passes energy to the frog The frog passes energy to the snake The snake passes energy to the owl

Energy Pyramid Shows the gaining (and loss) of energy along a food chain. Why would energy be lost as we move up the pyramid?

The Energy Pyramid Producers Bottom level of the pyramid Many of them get their food from the sun Example: plants, algae Consumers Body of the pyramid Get their energy from eating other organisms Example: herbivores, omnivores, carnivores

Herbivores, Omnivores, and Carnivores Eat producers (plants only) Only on the 2nd level of the pyramid Get 10% of producer’s energy Omnivores Eat producers and herbivores (plants and meat) On the 2nd or 3rd level of the pyramid Get 10% of producer’s or herbivore’s energy Carnivores eat only herbivores and omnivores (meat only) On the 3rd or 4th level of the pyramid Get 10% of herbivore’s or omnivore’s energy

What is this? Is it a producer or a consumer? Where does it get it’s energy from? producers What type of consumer is this? herbivore

What is this? Is it a producer or a consumer? Where does it get it’s energy from? sun

What is this? Is it a producer or a consumer? Where does it get it’s energy from? Producers, consumers What type of consumer is this? omnivores

What is this? Is it a producer or a consumer? Where does it get it’s energy from? All consumers What type of consumer is this? carnivores

Energy Pyramid **Most energy pyramids do not go any higher up because there is .1% energy so little energy at the top 1% energy 10% energy 100% energy Tertiary Consumers Consumers Secondary Consumers or Carnivores Primary Consumers or Herbivores Autotrophs Producers

Niche If an organism’s habitat is its address, its niche is its occupation Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions The role an organism plays in an ecosystem
