Food Chain

• A food chain shows how each living thing gets its
  food.
• A food chain always starts with plant life and
  ends with an animal.
• There are Omnivores, Herbivores, Producers,
  Carnivores, Decomposers in a food chain.

3
Producers

• Living things which take the non living matter
  from the environment, such as minerals and gases
  and uses them to support life.
• Green plants are considered producers and the are
  at the beginning of the food chain.

4
Decomposers

• These are the living things that feed off dead
  plants and animals.
• Examples are fungi, like mushrooms, and bacteria.
  

5
Omnivores

• People and Animals who eat both plants and
  animals.
• Unlike herbivores, omnivores can't digest some of
  the substances in grains or other plants that do
  not produce fruit

6
Herbivores

• A herbivore is an animal that gets its energy
  from eating plants, and only plants.
• Many herbivores have special digestive systems
  that let them digest all kinds of plants,
  including grasses.
• Many herbivores need lots of energy to survive
  and like cows and sheep eat all day long.

7
Carnivores

• A carnivore is an animal that gets food from
  killing and eating other animals.
• Carnivores generally eat herbivores, but can eat
  omnivores, and occasionally other carnivores.
• They help other species from getting
  overpopulated by eating them.

What does Energy Do?

• A food chain models the movement of energy in an
  ecosystem.
• The sun is the source of energy for the entire
  food chain.
• Plants capture about 1 of the light energy for
  photosynthesis.
• Herbivores consume about 10 of the plants
  biomass
• Carnivores capture and consume about 10 of the
  energy stored by the herbivores.

There is a difference

• Food Chains
• Food Chains follow a single path as animals eat
  each other.

• Food Webs
• Food webs show how many animals are
  interconnected by different paths.

Make your own!

• Most Food Chains only have 4 to 5 links.
