Food Chains and Food WebObjective:Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?

food chain
Food Chain

How energy in food molecules flows from one organism to the next

example food chain
Example Food Chain:

What type of consumers are here?

Who will get

the most energy out of this

food chain?

food chain1
Food Chain

What type of decomposer

could we add

to this food chain to add nutrients to the soil?

slide21
Which is the predator?

Which is the prey?

reality check
Reality Check
  • Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?
food web
Food Web

Contains lots of food chains.

Everything is connected and energy is being transferred in many ways!!!!!

food web example
Food Web Example
  • http://teacher.scholastic.com/ACTIVITIES/explorer/ecosystems/be_an_explorer/map/foodweb_play.htm
energy pyramids
Energy Pyramids
  • A diagram that shows an ecosystem’s loss of energy.

instructions
Instructions:

After your cut and paste, turn to page 75 complete the following pictures. You can title this page Food Chain and Web Pictures.

  • Draw a Food Chain. You must include a producer,2 consumers, and decomposer. Label each and use color
  • Draw a Food Web. You must include 2 producers, 4 consumers, and 2 decomposers. Label them and use color
symbiosis
Symbiosis
  • Objective:

Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?

symbiosis1
Symbiosis
  • Relationship where two organisms live in close association with each other.
3 types
3 Types:
  • Mutualism
  • Commensalism
  • Parasitism
mutualism
Mutualism
  • Both species benefit.
  • Butterfly benefits from getting nectar.
  • How does the flower benefit from this relationship?
commensalism
Commensalism
  • One organism benefits and the other one in unaffected.
commensalism1
Commensalism
  • One of the examples in the ocean is seen in sedentary crustaceans known as barnacles. These are very sedentary crustaceans, and so, they usually attach themselves to a substrate in the sea like rocks or preferably whales, seat turtles, etc. When whales and such creatures travel, the barnacles get access to nutrient rich waters and often, the morsels of food that are left behind by the whale, the barnacle catches it and eats it. These barnacles do the same thing when they attach themselves to the bodies of green sea turtles.

Reality Check
  • Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?
parasitism
Parasitism
  • One species, the parasite, benefits from the other species, the host, which is harmed.
