PCD Quiz Review


REVIEW:

What is a producer?

What is a consumer?

Name the four types of consumers

What is a decomposer?


1. Predator or Prey


2. What type of consumer


3. Producer or consumer??


4. What type of consumer?


5. What type of consumer?


6. What type of consumer?


7. Consumer or Decomposer?


8. What type of consumers?


9. What type of consumer?


10. What type of consumer?


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


1.FOOD CHAINS

NOTES


What do all organisms need in order to survive?

Energy!


Food Chain

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


Example Food Chain:

What type of consumers are here?

Who will get

the most energy out of this

food chain?


Food Chain

What type of decomposer

could we add

to this food chain to add nutrients to the soil?


Which is the predator?

Which is the prey?


Reality Check

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


2. FOOD WEB NOTES


Food Web

Contains lots of food chains.

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


Example Food Web:


Now paste your notes on page 72


Food Web Example

  • http://teacher.scholastic.com/ACTIVITIES/explorer/ecosystems/be_an_explorer/map/foodweb_play.htm


Energy Pyramids

  • A diagram that shows an ecosystem’s loss of energy.


Flow of Energy


Reality Check

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

DRAW YOUR OWN FOOD CHAIN AND FOOD WEB


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

  • Objective:

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


Symbiosis

  • Relationship where two organisms live in close association with each other.


3 Types:

  • Mutualism

  • Commensalism

  • Parasitism


Mutualism

  • Both species benefit.

  • Butterfly benefits from getting nectar.

  • How does the flower benefit from this relationship?


Mutualism


Commensalism

  • One organism benefits and the other one in unaffected.


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

  • One species, the parasite, benefits from the other species, the host, which is harmed.
